Comparative Analysis Of Domestic And International Titanium Alloy Standards

From China and the United States on titanium and titanium alloy standards promulgated by the situation, China's titanium and titanium alloy standardisation work with the foreign advanced level there is a certain gap. Weapon system in the standardisation of titanium alloy standardisation work with domestic aviation, aerospace and naval systems, there is a large gap, with foreign titanium alloy development and application and standardisation gap is even greater. This has a lot to do with the characteristics of weapons equipment and titanium alloy application level, the current application of titanium alloys for weapons equipment is only one - TC6 (GB/T 3620.1-1994 "titanium and titanium alloy grades and chemical compositions" and GB/T2965) GB/T 3620.1-1994 Titanium and Titanium Alloy Grades and Chemical Composition and GB/T 2965-1996 Titanium and Titanium Alloy Rods). All-titanium lightweight flamethrowers have been mass-produced and formally equipped with troops, using industrial pure titanium, T-3Al-2.5V and Ti-451 alloy. China in the 1970s to carry out the titanium airborne mortar development. 100 mm mortar floor using TA7 alloy whole stamping and become, titanium bottom plate than steel bottom plate is 10 kg lighter. then, and developed a 82 mm all-titanium airborne mortar, and steel 82 mm mortar compared to the weight reduction of 16.6 kg. titanium alloy in the weapon is rarely used.
