The difference between titanium and titanium alloys

The difference between titanium and titanium alloys

Is elemental titanium rings, titanium alloy is a mixture. Thus the nature of the titanium alloy having a more diverse and more extensive use.
Concept definition Titanium: titanium-based alloy is added to other elements of the alloy known as titanium. Titanium has a low density, high strength, corrosion resistance, good process performance, etc., is an ideal material for aerospace engineering structures.
Scope of the study: the structure of titanium and titanium alloys can be divided into heat resistant titanium, titanium alloy or α, β-type titanium alloys and α + β type titanium alloy. Scope of the study also includes forming technology of titanium alloys, powder metallurgy technology, rapid solidification technology, titanium and other military and civilian.
Titanium is a new structural material, it has excellent performance, such as low density (~ 4.5g · cm-3), high specific strength and fracture toughness, fatigue strength and resistance to crack growth is good, good low-temperature toughness, excellent corrosion resistance, the maximum operating temperature of some titanium alloys for 550ºC, is expected to reach 700ºC. So it gets in the aviation, aerospace, chemical, shipbuilding and other industrial sectors increasingly widely used, is developing rapidly. (Σ0.2 / density) versus temperature of light alloy, steel, etc., stronger than titanium rods than other light metals, steels and nickel alloys, and this advantage can be maintained to about 500ºC, so some titanium alloys suitable for manufacturing gas turbine components. Approximately 80% of titanium production for the aviation and aerospace industries. Airframe structural materials such as the US B-1 bomber, the titanium about 21%, mainly used in the manufacture of the fuselage, wings, skin, and bearing components. Airframe structural materials F-15 fighter, the titanium alloy with a capacity of 7000kg, accounting for about 34% of the weight of the structure. Boeing 757 aircraft structural parts, titanium or about 5%, with a capacity of 3640 kg. McDonnell Douglas (Mc-Donnell-Dounlas) produced by DC10 aircraft alloy with a capacity 5500kg, accounting for more than 10% of the weight of the structure. The amount of titanium in the chemical and general engineering areas: United States accounts for about 15% of its production in Europe accounts for about 40%. Due to the excellent corrosion resistance of titanium and its alloys, good mechanical properties, as well as qualified histocompatibility, making for the production of biological materials such as prosthetic devices.
