How to Choose Sintering Methods for Titanium-Zirconium-Molybdenum (TZM) Alloy? 272

The earliest produced in the industry is titanium-zirconium-molybdenum (TZM) alloy, which is a molybdenum alloy containing 0.4%-0.55% titanium, 0.06%-0.12% zirconium and 0.01%-0.04% carbon. The total amount of alloying element does not exceed 1%. There are two main sintering methods for titanium-zirconium-molybdenum alloy: hydrogen protection sintering and vacuum sintering as following: 1.Hydrogen protection sintering: the product is sintered under the protection of hydrogen. During the process, due to the reduction effect of hydrogen, the oxides in the molybdenum powder will be…
