Titanium, zirconium and molybdenum alloy production process
The production process of titanium, zirconium and molybdenum alloy is as follows: mixing - milling - pressing - sintering - rolling - annealing - processing - finished product. Commonly used production methods for zirconium-titanium-molybdenum alloy (TZM alloy) are: arc melting and casting and powder metallurgy.
The specific production process of powder metallurgy is as follows: mix high-purity molybdenum powder with TiH2 powder, ZrH2 powder, and graphite powder in proportion. After cold isostatic pressing, the TZM blank can be obtained by high-temperature sintering in a protective atmosphere.
The blank undergoes 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 to obtain the TZM alloy.
The arc melting casting method melts molybdenum, and after melting it is doped with a certain amount of Ti, Zr and other alloying elements, and then uses conventional casting methods to produce TZM alloys.
