titanium alloy plate is a new and important structural

Titanium is a new and important structural materials used in the aerospace industry , the proportion between the aluminum and steel , strength and temperature ranged , Medical grade titanium alloy but has high strength and excellent resistance than seawater corrosion and ultra- low temperature performance. In 1950 the United States for the first time in the F-84 fighter-bombers used after the fuselage insulation panels, wind shield , tail cover other non- load-bearing components. 1960s began using parts from titanium alloy fuselage toward the rear of the fuselage , in part, to replace structural steel bulkheads , beams, rails and other important flap bearing components . The amount of titanium in military aircraft is increasing rapidly , reaching 20 % to 25% by weight of the aircraft structure . Since the 1970s , began extensive use of titanium civilian aircraft such as the Boeing 747 aircraft with a capacity of 3640 kg or more of titanium . Aircraft Mach number of less than 2.5 primarily to replace the titanium steel , to reduce structural weight . Again , the U.S. SR-71 high-altitude reconnaissance aircraft speed ( Mach 3 at an altitude of 26,212 meters ) , 93% titanium by weight of the aircraft structure , known as " all-titanium " aircraft . When the weight ratio of aircraft engines, increased from 4-6 to 8-10 , a corresponding outlet temperature from compressor 200 ~ 300 ° C to 500 ~ 600 ° C , medical grade titanium the original plate is made of aluminum and the blades of the low pressure compressor must switch to titanium , or titanium instead of stainless steel plate and high-pressure compressor blades in order to reduce the structural weight . 1970s, the amount of titanium in the general aviation engines accounted for 20% to 30% of the total weight of the structure is mainly used in the manufacture of compressor components such as forged titanium fan, compressor discs and blades, cast titanium compressor casing , intermediate casing, bearing housing and so on. The main advantage of the spacecraft 's high- strength titanium alloy , corrosion resistance and low temperature performance to manufacture all kinds of pressure vessels, fuel tanks , fasteners, instrument straps, architecture and rocket shells. Sputnik , the lunar module , manned spaceship and space shuttles are also using titanium plates welded .

titanium alloy plate Transient stability of domestic titanium City recently

Chinese titanium sponge titanium temporarily stable overall market decline in value

Transient stability of domestic titanium City recently . International Titanium seeds, ilmenite European market demand continues to slump , weak turnover , while the North American market is relatively stable ilmenite , the U.S. and titanium alloy plate‍ Canadian producers have said that at present , ilmenite trading activity is relatively stable, market supply and demand balance , there is not much changes , the current price is relatively strong, think short term, it will not be much fluctuation .

Domestic titanium seeds, titanium sponge recent decline in value caused widespread concern of market participants . Currently , the price of titanium sponge has been way down, 0 titanium sponge by last month 's price 65000-70000 yuan / ton , has been falling now 62000-64000 yuan / ton, the market reflects the business and even now traded titanium sponge in fact, the price is lower than the current price , 0 titanium sponge in the market at 60,000 , 60,000 or even less than the price could get arrived.

However, according to understand that the titanium sponge prices have dropped a lot, because of the bearish outlook , buyers are currently low market inquiry , but manufacturers insist on quoted market prices remain unchanged , at present , the domestic part of the titanium sponge manufacturers adhere to market price 0 65,000 yuan / ton , a market price of 64,000 yuan / ton, but the market traded market prices have declined , although , at present , the mainstream transaction prices have fallen to 0 62,000 yuan / ton , about a 60,000 yuan / ton.

The market outlook , there are manufacturers that titanium rod stock‍ titanium tetrachloride , titanium tetrachloride possibility outlook fell sharply small. Because the market oversupply situation has improved , the market supply is not much, the price would no longer fall down .

Bottomed titanium tetrachloride , titanium sponge still not keep up with market demand , according to the manufacturers , the current decline in the price of titanium sponge , or keep up with demand for its market , buyers inquiry prices are low, manufacturers profit is limited, the price is too low, can not hold stocks , the market volume is also not much of titanium sponge manufacturers are engaged in a tug of war with the market , and with the arrival of the end of titanium sponge market demand continues to cool , and manufacturers need capital returns , reduce inventory , market price or to compromise , come down .

Ilmenite current situation is relatively stable, Shanghai spot aluminum price of 16100-16140 yuan / ton, was up 80 yuan , titanium tube stock‍ China also reported up through the spot price of aluminum , ferro-titanium raw material prices are currently strong, though still insufficient market demand , but by the cost support, the market is still relatively stable, the recent market prices would not be a substantial adjustment , will remain stable.

And the recent poor weather conditions , the domestic titanium round bar‍ ore market tensions have emerged , Panzhihua regional market demand, prices will strongly manufacturers , market participants have predicted the subsequent market prices will rise , but the short term , due to the recent market transactions downstream titanium dioxide not very good, there is a certain decline in market confidence , yet the opportunity to raise prices , titanium ore market will stabilize over time.‍

titanium round bar cast titanium alloy plates smaller

Casting and mechanical properties of titanium plate deformation difference 

The mechanical properties are usually cast titanium plates titanium round bar‍ are below the performance of similar titanium plate deformation, especially in the plastic show more respect for the highlight, which is mainly due to the results of casting and casting defects organizational constraints, cast titanium alloy plates smaller than the other properties of the cast alloy drops. 

     For example, the yield strength titanium alloy casting fell only 13%, titanium wire manufacturers‍ while 60% ​​of the small decline in aluminum, steel declined by 25 percent, cast nickel-based alloys decreased by 17%, which illustrate the performance characteristics and deformation of cast titanium with titanium rivaling negative energy characteristics, and in some ways even more than the deformation titanium round bar‍ properties of titanium, especially in fatigue performance.

titanium plate for sale Due to simplify the learning activity

How the development of titanium tube casting process 

  At present, the domestic technology of cast titanium tubes titanium round bar‍ have carried out some research and development work has evolved from the initial simple graphite casting process to the coexistence of multiple process steps, their level has been greatly improved. Casting titanium tube is quite extensive, almost all already known to use cast molding method. Recently, more widely used in the production process is machined graphite, graphite tamping precision investment casting and ceramic shell mold casting process. 

     Due to simplify the learning activity of titanium alloy tube has, titanium wire manufacturers‍ making it the casting process is different from iron-and nickel-based alloy, and has many unique features, which is mainly manifested in the choice of mold material. Cast titanium tube holding type material used must have a high chemical stability, high thermal shock resistance, low moisture absorption capacity and low titanium round bar‍ thermal resistance, complete with mold material at these performance requirements are still being explored.

titanium alloy plate If the cyclic heat treatment

Impact on performance titanium heat treatment cycle 

The phase transition in titanium stress is small, with a simple heat treatment, it is difficult to change the original casting organizations, especially the grain titanium sheet suppliers‍ boundary organization. 

To refine casting titanium organization, people were cycling in the heat treatment. Volume effect of the use of the accumulation phase, resulting in 

And increased stress, prompting recrystallization, resulting in multilateral and grain refinement sheet of tissue. 

     Experimental results show that the alloy has Ti6A14v thick widmanstatten, the P-phase region through a ten cyclic heat treatment (980 a 

500 ℃), enables thin sheet first roughening, titanium wire manufacturers‍ and broken off, so that the structure refinement. Then a continuous grain boundary is not 

Change, and even some coarsening. If the cyclic heat treatment (980 a 500 ℃, 10 times the water-cooled ten 900 ℃, 2h air-cooled) before pre-

P first heated to a broken fire zone (1010 ℃, water quenching), become fully martensite after cycle heating and cooling, a grain boundary 

Disappeared or broken off, the degree of titanium round bar‍ refinement and organizational uniformity will increase its alloys have significantly improved fatigue performance.
