TZM alloy

TZM alloys (molybdenum zirconium titanium alloy) are commonly prepared by arc melting - casting and powder metallurgy. TZM alloy rod arc melting casting method is to melt pure molybdenum by arc and add a certain amount of alloy elements such as titanium and zirconium by weight percentage, and then use the conventional casting method to get TZM alloy (molybdenum zirconium titanium alloy). Powder metallurgy has unique chemical composition and mechanical and physical properties, which cannot be obtained by traditional casting methods. The high purity molybdenum powder, TiH2 powder, ZrH2 powder and graphite powder were mixed in proportion and formed by cold isostatic pressing, and then sintered at high temperature under protective atmosphere to get TZM blank. After high temperature hot rolling (high temperature forging), high temperature annealing, medium temperature hot rolling (medium temperature forging), medium temperature annealing to eliminate stress, and then warm rolling (warm forging) to get TZM finished material. The rolling (forging) process and subsequent heat treatment of billet have great influence on the properties, anisotropy and texture of the material. The use of powder metallurgy can save the vacuum consumable electric arc furnace, large extruder and forging hammer and the corresponding high temperature heating furnace and other large equipment, so that the process is simplified, the production cycle is shortened, the energy consumption is reduced, the production capacity and the rate of finished products are doubled, so the cost is greatly reduced. TZM alloys (molybdenum zirconium titanium alloy) are usually prepared as rods and plates. Powder metallurgy can save vacuum consumable electric arc furnace, large extruder and forging hammer as well as the corresponding high temperature heating furnace and other large equipment, so that the process is simplified, the production cycle is shortened, consumption is reduced, production capacity and product rate can be improved, so the cost is greatly reduced.
