WHAT IS TITANIUM ALLOYS? GRADES, APPLICATION AND PROPERTIES

Properties of Titanium Alloys

The characteristics are related to carbon, nitrogen, hydrogen and oxygen impurity content. Titanium iodide has a cleanliness of less than 0.1%, but has low strength and high plasticity. 99.5 per cent industrial pure titanium has the following characteristics: density p=4.5 g / cubic centimeter, melting point 1725 ° C, thermal conductivity a=15.24W/(m. K), stress strengthb=539MPa, elongation delta=25%, elastic module E=1.078* 105, hardness HB195, shrinkage= 25 per cent.

Because of its unique strength and creep resistance, Commercially pure titanium is stable up to temperatures of about 300 ° C. Even at temperatures up to around 500 ° C, more complex titanium alloys are strong. The strength of fatigue (10 ^ 7 cycles) is approximately 50 percent of the stress, and welding causes no significant decline in the strength of fatigue.

What is the best grade titanium?

Grades 1, 2, 3, and 4 of titanium are commercially pure (99% titanium minimum). That grade has minor chemical composition variations that affect the mechanical characteristics and capability of the design. The resistance to corrosion in all four levels is identical. Titanium Grade 2 is the preferred alloy for most industrial applications with good flexibility and corrosion resistance between four commercially pure (C.P.) grades of titanium. Grade 3 is least used in commercially pure titanium but is not less valuable. Grade 3 is stronger and less formable than grades 1 and 2, but has higher mechanical components than its predecessors. Grade 3 has a ductile character.

Grade 2 provides excellent seawater resistance and a marine corrosion atmosphere. The resistance to oxidation of four commercially pure is close. Grades, but with different oxygen and iron contents, mechanical properties vary. Grade 2 titanium is resistant to wet chlorides, metal chloride, chlorite and hypochlorite, nitric and chromic acids, organic acid, and many other industrial gaseous applications.

Application Of Titanium Alloys :

Titanium alloys have high strength, low density, excellent mechanical properties, heavy durability, and resistance to corrosion. Titanium alloy is also weak in manufacturing and hard to cut. Impurities like hydrogen, oxygen, nitrogen, and carbon can be easily absorbed in warm work. Wear resistance is also low, and the production process is complicated. In 1948, automated titanium production began. The titanium industry is growing with the growth of the aviation industry at an average annual level of 8%. The world's annual production of titanium alloy processing materials amounts to over 40,000 tonnes, and approximately 30 titanium alloy forms are available.

SHIPPING FIELD :

Boats and other appliances have long been immersed in water so that the components need to be resistant to corrosion, durable, and long-lasting. Thanks to their full strength scope, unique physical properties, excellent mechanical performance, and resistance to corrosion and damage, titanium alloys are widely used in vessels. On pumps, filters, tubing, fire extinguishing devices, boats, and other equipment of Russian ships, Titanium alloys are used.

Aerospace applications :

In fuselage, engine, and rocket parts, titanium is an essential "space material." When designing high-performance aircraft, such as ASX-31, X-30, the use of titanium alloy materials has produced remarkable results. The M coefficient has risen by approximately three, while the aircraft's overall quality is down by 80%. Russia provides titanium alloy sheets and other raw materials in the manufacturing of aviation equipment. For research and development for Shenzhou Spacecraft in China, titanium alloys have been commonly used.
