Titanium alloy has been widely used in the weapon industry and has become an indispensable material. With titanium, weapons have become more powerful and more powerful. Titanium alloy weapons are not only light in weight, good maneuverability, but also increased in power. They are especially suitable for airborne troops and assault troops. Titanium alloy mortar seat plates are more than 50% lighter than steel plates. Titanium alloys are used to make mortar tubes, seat plates, High-quality materials such as barrels and gun mounts are also good materials for preparing protective clothing and helmets.

Since the industrial production of titanium and titanium alloys in the mid-1940s, the United States and the Soviet Union have begun to pay attention to and study their applications in weapons. The Watertown Ordnance Factory of the United States has made many developments in the application of titanium alloys in weapons. Sexual work is the largest and most advanced unit in the world to study the application of titanium alloys in the field of weapons. In 1955, the US weapon industry used 57 tons of titanium, 281 tons in 1961, and 1,040 tons in 1971. It is estimated that it will reach 2,100 tons in 2020. Because it is a non-war period, the growth rate is not fast.
The application of in artillery
Titanium and titanium alloys are important materials for the manufacture of artillery structural parts. Since the 1950s, they have been used in some world-famous artillery. The barrel, chamber, nozzle and launch piston of the M28 120mm Crockett recoilless gun manufactured in the United States in 1950 are forged and extruded with Ti-6Al-6V-2Sn-0.5Fe-0.5Cu alloy The mass of the whole gun is 68kg, which is 34.9% lighter than the 104.4kg of the steel gun. After splitting, 5 people can easily carry it back. In 1961, mass production began, equipped with infantry battalion, paratrooper battalion, mechanized infantry battalion, tank battalion and The airborne division has the advantages of small size, light weight, great power, high maneuverability and easy camouflage. TI-6Al-6V-2Sn-0.5Fe-0.5Cu is a (α+β) type alloy. The mechanical properties of the annealed state are: tensile strength 1098MPa, yield strength 1030MPa, elongation 13%, and section shrinkage rate 37% , Brinell hardness 34.
In the 1970s, Ti-6Al-4V-2Sn titanium alloy was used to make barrels, and Ti-6Al-4V, Ti-7Al-4Mo and Ti-5Al-1.5Fe-1.4Cr-1.2Mo titanium alloys were used to make the gun barrel. , Nozzle and launch piston, the mass of the whole gun is only 49kg, 4 people can resist running forward. After the T66 type 76mm gun’s tailstock and gun mount were changed to titanium alloy, it was 93.55kg lighter than steel, only 142.9kg. The large titanium frame of the wild gun is 42% lighter than the steel. Later, the United States used industrial pure titanium to manufacture the seat plate of the T227 81mm mortar, which was 50% lighter than the steel plate, only 10.9kg. The plug of the gun is also made of titanium alloy, which is used to connect the barrel and the seat plate. Hundreds of test shots have been carried out on the ground and on the gravel ground, and good results have been achieved. After the T227 81mm mortar was replaced with a titanium seat plate, the mass dropped to 34kg and the range increased to 4500m, while the steel gun had a mass of 42.25kg and a range of 3,600m. Not only did the mass decrease by 20%, the range increased, and it was more maneuverable. To improve.
After Japan’s 155mm chase mount plate was replaced with Kobe Steel's titanium alloy, the quality was reduced by about 50%. The 5mm and 8mm Ti-6Al-4V alloy plates were used for welding. Tests showed that the welding quality is good and can fully meet the combat needs. . The 100mm mortar seat plate made of TA7 alloy in Japan is 10kg lighter than the steel plate. It was designed and finalized in 1981 and produced and installed in 1983. The body, base and bracket of the 82mm mortar installed in 1984 were changed to titanium alloy, which was 16.6kg lighter than steel.
On January 31, 2007, the US "Army Times" stated that the 155mm M777 new howitzer is the first ground combat system made of titanium alloy, which is about 3150kg lighter than the obsolete M198 artillery, and its mass is reduced by nearly 50%. The decline in the quality of the artillery system has not affected its range and accuracy, but its mobility has been greatly improved.
Helmet, body armor and other equipment.
From 1959 to 1961, the United States used Ti-6Al-4V and Ti-5Al-2.5Sn titanium alloys to spin M-1 standard helmets without success. Later, they switched to Ti-4Al-3Mn titanium alloys and explosive forming processes. The mass is only 0.794kg-1.02kg. In terms of bulletproof effect, the titanium helmet is the same as the steel helmet, but the titanium helmet is 0.45kg lighter than the standard steel helmet.
The United States uses a 25.4mm thick sheet composed of 10 layers of nylon and 1 layer of Ti-5Al-2.5Sn titanium alloy sheet to manufacture bulletproof vests. Its mass is only 3.86kg. It can resist shells, grenades, and mine fragments, but not 7.62mm. bullet.
The muzzle brake of the Russian Union 152mm double-barreled self-propelled gun is made of titanium alloy. It has two barrels, which are used alternately when launching. The launch speed is fast and the firepower is strong, reaching 15-18 rounds per minute; it is flexible and has an off-road capability. Strong, and strong survivability.
China has been studying the application of titanium alloys in weapon manufacturing since the 1970s, and the results have been remarkable. The anti-tank missile steering gear and frame are made of TC9 titanium alloy, which is a Ti-0.2Pd α alloy, which is used in the annealed state; the 85 type anti-aircraft machine gun brake made of TC4 titanium alloy has achieved very good results Later, the use of precision casting ZTC4 alloy to replace TC4 alloy extruded bars achieved better results. The material utilization rate rose from 18% to 94%, and it also saved a lot of cutting costs, which achieved two goals. TC4 is a commonly used Ti-6Al-4V alloy with excellent properties, α+β type, used in the annealed state. The light flamethrower made of titanium has a range of up to 70m. It is a close-range light weapon, which is more than 3kg lighter than that made of steel. It can be made of industrial pure titanium, Ti-3Al-2.5V and other alloys.Involving the titanium sheet grades:6 4 sheet,grade 9 titanium sheet,6al4v titanium plate.
