Rolling and forging are two common processes for making titanium and titanium alloy wire.
1.Rolling
The rolling process mainly uses titanium and titanium alloy wire blanks (coiled or single) as raw materials, and obtained coiled or single wire products by drawing, including titanium iodide wire, titanium molybdenum alloy wire, Titanium-tantalum alloy wire, industrial pure titanium wire and other titanium alloy wire, their key application fields are different.
For example, titanium iodide wire can be used in industrial sectors such as instruments, meters, and electronics. Titanium molybdenum (Ti-15Mo) alloy wire is often used as the source material of ultra-high vacuum titanium ion pump. Titanium-tantalum (Ti-15Ta) alloy wire is a getter material for the ultra-high vacuum industrial sector.
Industrial pure titanium and other titanium alloy wires mainly include industrial pure titanium wire, Ti-3Ai wire, Ti-4A1-0.005B wire, Ti-5A1 wire, Ti-5A1-2.5Sn wire, Ti-5A1-2.5Sn-3Cu- 1.5Zr wire, Ti -2A1-1.5Mn wire, Ti -3A1-1.5Mn wire, Ti -5A1-4V wire, Ti -6A1-4V, etc., are commonly used as corrosion-resistant parts, electrode materials, welding materials, etc. High-strength TB2 and TB3 alloy wires are used in aviation and aerospace.
2.forging
The forging deformation process is the most important means to ensure the ideal properties of titanium alloy materials. At present, more than 80% of industrial titanium alloys are used as deformed titanium alloys, such as forgings, forging bars and rolled profiles.However, incorrect forging process often causes some bad metallurgical defects in titanium alloy products, which will continuously deteriorate their mechanical properties, thus causing potential harm to the normal use of titanium alloy products, and also causing a lot of waste to production and use manufacturers.
Common forging defects in titanium alloy processing mainly include overheating and uneven structure, voids, cracks, etc. These defects are mainly caused by improper control of process parameters during the forging process of titanium alloy products.Generally, They are very easy to find in the microstructure inspection or ultrasonic testing of titanium alloy products.Through research and analysis, in order to prevent the occurrence of forging defects, we can choose suitable forging equipment according to different characteristics of titanium alloy materials in the forging process to control the deformation rate, forging heating temperature, pass deformation and cooling rate after forging.
