How to get titanium zirconium carbon(TZC alloy)?
Titanium zirconium carbon(TZC alloy) Chemical Composition:
Mo + 1.2% Ti + 0.3% Zr + 0.1% C
TZC alloy is preparaed by powder metallurgy and vacuum arc melting.
The presence of carbon leads to the formation of the hard carbide dispersed phase,allowing the alloy to be strengthened. Using a vacuum arc melting and powder metallurgy processing side in the industrial production of this alloy method, a vacuum melting of pure molybdenum percentage by weight Ti, Zr, etc. Adding a certain amount of alloying elements, and then TZC alloy by arc melting method.
Powder metallurgy rule is uniformly mixed in proportion with high purity molybdenum powder and TiH2powder, ZrH2 powder and spray carbon black powder after cold isostatic pressing, and then high-temperature sintering under a protective atmosphere to give TZC dough.
Blank and then through the high-temperature hot-rolled (hot forging), high-temperature annealing, the temperature of hot-rolled (isothermal forging), the temperature annealing to eliminate stress and temperature rolling (the warm forging) get the TZC alloy finished.
Billet rolling (forging) process and subsequent heat treatment on the properties of the materials, anisotropic structure has a greater impact. Processed using powder metallurgy the TZC alloy sheet and bar.
It can save the vacuum consumable arc furnace, large extruder and the corresponding high-temperature furnace and other large equipment, simplify the process, shorten the production cycle, reduce energy consumption, production capacity and the yield can be improved, thus greatly reducing costs.
