titanium plate and wheelchair in the field

Titanium frames for bicycles and wheelchairs are formed in the mid-1980s , the application of the fast development of titanium , but just when the market began to heat these small , slow down the application process in the world of titanium .

A bicycle frame

In recent years due to defense cuts and uncertainty from floating aircraft industry , the U.S. production of V pipe three companies turned to the bicycle industry , but the world has been produced by a bicycle frame nor 3AI-2.5V to three Boeing 747 aircraft titanium (130t). Currently there are nearly 50 companies producing titanium bicycle , 90 percent of the world's all-titanium frame from several original equipment manufacturers (OE), 10% of the remaining half is produced by the United States itself , the United States has always already is the largest titanium bicycle producer and consumer countries .

This year is likely to be the highest annual sales of titanium frame , probably will produce 17,000 titanium frame , with a total weight of about 27 \ Materials Price $ 5,000,000 , including full titanium tubing, rods and plates .

When the benefits of a growing number of cyclists begin to understand titanium , but feel strapped , with air quality pipe production of Ti-3Al-2.5V frame , each pair of prices between 1600 and $ 3500 the whole bike selling price from $ 2400 to $ 6000 . In the past four years, commercially pure titanium tubes and non- aviation penalty -3AI-2. SV ( Sports Grade ) titanium frame made ​​popular , some sports grade titanium frame lowest retail price $ 1,000 per pair , the whole bike lowest price $ 1,700 . 1985 purchasing power with titanium frame is zero in 1990 to approximately $ 1.5 million by the end of 1995 , the purchasing power of approximately $ 5,000,000 .

2 Bicycle Parts

The bicycle component is the crankshaft connected to the positioning frame , pedal , steering wheel , etc., than the titanium member industry penalty -3 Si 1-2.5V faster frame industry , most of the parts with Ti-6AI- 4V production , mostly bar or plate processing machine parts out . Member with the Ti-6A1-4V Ti-3 bleed strength of only one frame of a 2.5V / 3 , 1997 to approximately 10t. SB cast components can increasingly common development in this respect may be greater than the slow development of machining parts , titanium supplier of titanium parts manufacturers began to offer cheaper materials , most of these low-cost bicycles grade material is actually being elimination of aeronautical materials .

3 wheelchair frame and components

Unlike in many market areas wheelchair bicycle market , the most important difference is that only a small amount of production of titanium wheelchair frame , with most of the slit pipe production of commercially pure titanium , titanium wheelchair total strength of approximately 15t.

Currently only a few companies in the United States has sufficient research and development funds to develop titanium wheelchair or purchase materials. Compared to cheaper aluminum wheelchair, wheelchair few advantages of titanium , titanium screw bolts now in addition ,titanium rod the titanium wheelchair parts industry has not yet formed , although there is a market , but very small, included only a small number of consumable parts , size of the market has not to $ 1,000,000 .

4 Material Requirements

Compact , stiffness , light weight bicycle and wheelchair drive specification for general requirements , titanium is often not the best material, and wrought aluminum and aluminum more popular , if titanium metal matrix composites (MMCs) , then the price down , may become a substitute for some of the aluminum market applications .

Bicycle rack

Material requirements of the frame is very simple, but it is particularly critical driving characteristics , so that the choice of materials in some ways more complex, most of the means of transport, structural elements and internal facilities and operating elements are separated, until recently , all the requirements of the bicycle frame suspension having structural integrity and function .titanium stockists Titanium is not yet a bicycle designed specifically for only some of the material is improved for a bicycle , most people consider to reduce the cost, but the main problem facing the receiving member is a rigid titanium rather than cost .

β stabilizing element in titanium and titanium plate in

β stabilizing element in titanium and titanium alloys mainly from the solid solution strengthening and stabilizing β phase. When β stable over a certain number of elements , titanium has a strengthening effect of heat treatment .

Adding a small amount of β stabilizing element in a form close to a titanium alloy titanium alloys .medical titanium bars This alloy has a weak effect of heat strengthened . Eutectoid elements can be increased quickly at room temperature and high temperature properties of titanium alloys by precipitation compounds. In the heat is often a small amount of titanium silicon , such as TA8 so on.

In a + β titanium alloys to improve the content of such elements can improve the hardenability of the alloy, titanium metastable β titanium apparently hardenability highest . However, when used eutectoid elements should prevent the formation of compounds , causing brittleness. Use of such diverse elements should follow a small number of principles, such as TC10 titanium alloy used in 0.5% Fe and 0.5% Cu, increasing the solid solution strengthening effect. In the heat of a + β titanium alloys are often added to a small amount of fast- silicon eutectic elements to improve creep resistance .

In the β -type alloys , β is the main component of the stabilizing element . They hand the β phase retained, on the one hand from the solid solution strengthening effect . TB1 and TB2 alloys are used a lot of the same eutectic crystal elements and elements work together . At this point should also be noted that the amount of eutectoid elements added to try to avoid precipitation of compounds.

High molybdenum , high niobium titanium stabilized β is an excellent corrosion resistance to reducing media materials titanium axles. Plus palladium cobalt corrosion resistant materials and processing have long been used in foreign countries .

Heat treatment of titanium and titanium plate changes during cooling

When titanium and titanium alloy is heated to β phase, polymorphic transition a → β will occur. This process is also sometimes referred to as recrystallization. The highly pure titanium a → β transition temperature of 875 + -5 ℃. But until the β-phase fully formed, it is difficult to observe this process by optical method. In the low temperature phase β of the reason is unclear. But the experiment indicated,titanium stockist a mutual transition and β, either heating or cooling, a phase and β phase always maintain a certain Bragg Sites of the relationship. Polymorphic transformation of titanium when heated little research to date.

1 change in the slow cooling of titanium and titanium alloys
When titanium and titanium alloy is slowly cooled from β-phase region to a + β phase region, β → a polymorphic transformation to happen. In the high-titanium has been confirmed at this time of nucleation is a martensitic phase, and then grow by thermal activation process. When nucleation of the embossed surface of the sample usually also the martensitic transformation, but also to maintain a strict phase Sites of the Bragg relationship between the parent.

2. Changes in the rapid cooling of the
Changes and changes in product titanium and titanium alloy occurs when rapid cooling from the β phase region with changes in β stabilizing element content is different.

Martensitic transformation: 1.a `massive martensite orientation relationship can not be measured; acicular martensite and β phase to maintain a` Bragg Sites of the relationship habit plane is (334) β or (344 ) β. 2.a "in Ti-Mo, Ti-W, Ti-Re was found, but the Ti-V system did not; a" lattice parameter with composition changes; a "titanium plastic is reduced.

Phase formation quenching ω: ω is the size of small particles by electron microscopy observations only;titanium standard parts ω elastic modulus and hardness, the plastic drop.

Titanium and titanium plate solid solution and aging treatment

Solution and aging treatment is a primary means of heat treatment of titanium and titanium reinforced . It is actually divided into solution treatment and aging treatment carried out in two steps . Solution treatment is to titanium and titanium alloy heating, insulation and rapidly cooled to room temperature operation. Aging treatment after solution treatment is the workpiece at a medium temperature range (450-550 ℃) holding a certain time after the air-cooling operation. This heat treatment method can be applied to nearly α alloy , α + compound alloy , α + β alloy and heat-treated β alloys.
Solution treatment process selection
The purpose of titanium and titanium alloy solution treatment can be effective is to keep strengthening the metastable phase . For near α and α + β type alloys , the purpose is to retain the solution treated martensite α ', α " or the amount of metastable β phase . Solution treatment temperature is usually lower than the phase transformation point selection 40-100 ℃ at this time , a certain proportion of primary α phase β -phase . β produce metastable phase in the subsequent rapid cooling . generally require cooling water quenching oil quenching may also be used it should be emphasized that these two alloys hardened be sure to quickly . delayed quenching time ,medical titanium plate product temperature decreased rapidly , α -phase nucleation in the first phase on the original β grain boundaries and grew up on the mechanical properties of hardened state . gives the quench delay operations on TC4 alloy and affect performance . usually require quench delay time can not be more than 10 seconds on the sheet even more demanding. Additionally, the complex shape of the workpiece or sheet should be taken to prevent deformation hardening .
The purpose of metastable alloy solution-treated in order to preserve the metastable β phase . Solution treatment temperature is usually selected in the α + β / β transformation point 40-80 ℃. Cooling can be air-cooled and water-cooled . To prevent deformation hardening and improving economic results generally use air cooling.
Α + alloy for some compounds , the purpose is to keep the processing solution supersaturated solid solution of β . Solution treatment temperature is generally selected just below the eutectic temperature. Such as Ti-2Cu alloy eutectic temperature of 798 ℃, the solution treatment temperature selection at 790. ℃ Cooling optional air cooling.
Incidentally , since the titanium and titanium alloy produced in the solution treated martensite on replacement elements are oversaturated not result in a large lattice distortion ,titanium pipe such as titanium martensitic steels martensitic not so hard . In addition, the intensity of metastable β phase is relatively low . Therefore , hardenability titanium and titanium alloy does not mean depth of hardening after quenching , but rather the depth of those retained in the subsequent aging in Asia can cause hardening of the stable phase. Because titanium martensite on cooling rate to be much more sensitive , it is hardening during tempering is also limited, so hardenability titanium and titanium alloy mainly refers to the depth of retained metastable β phase.
