TZM alloy

The common preparation methods of TZM alloy include 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 Ti and Zr according to the weight percentage, and then get TZM alloy (molybdenum zirconium titanium alloy) by conventional casting method; Powder metallurgy has unique chemical composition and mechanical and physical properties, which can not be obtained by traditional melting and casting. The high purity molybdenum powder was uniformly mixed with TiH2 powder, ZrH2 powder and graphite powder in proportion, and then formed by cold isostatic pressing, and then sintered at high temperature in a protective atmosphere to obtain TZM billet. The billet is then hot rolled at high temperature (high temperature forging), annealing at high temperature, hot rolled at medium temperature (medium temperature forging), annealing at medium temperature to eliminate stress, and then warm rolled (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 method 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 increased, so the cost is greatly reduced. TZM alloy (molybdenum zirconium titanium alloy) is usually prepared into bars and plates. Powder metallurgy method 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 consumption is reduced, the production capacity and the yield can be improved, so the cost is greatly reduced.

TZM alloy has a high melting point, high strength, high elastic modulus, linear expansion coefficient, low vapor pressure, good thermal conductivity, corrosion resistance strong and good high temperature mechanical performance characteristics, thus can be widely applied in many fields.

TZM alloy (titanium zirconium molybdenum) the many advantages it broad range of applications. Their performance under high temperature and pressure out of the good mechanical properties make it more on the military-industrial applications, such as engines with the valve body, rocket nozzles, gas pipeline, the nozzle throat insert; Color Picture Tubes and used production line glass furnace with platinum and rhodium clad agitator spindle is to use its liquid metal corrosion resistance;
TZM is an established Molybdenum alloy (0.50 Ti, 0.08 Zr, balance Mo), which is consolidated by either the P/M or vacuum arc-casting processes. It gives excellent service in applications that require high strength and creep resistance at elevated temperatures. TZM Molybdenum Alloy also permits higher service temperatures without softening or weakening.

A major attribute of our vacuum arc-casting process is the superior result, which can be obtained in alloying. In the vacuum arc furnace, complete melting and blending of the molybdenum and alloys takes place to assure a homogeneous material.

Shaanxi Zhuohangxin Metal Materials Co. LTD  www.ti-metals.com   produces a wide range of molybdenum and molybdenum alloy mill products using two primary consolidation methods; vacuum arc-casting (VAC) and powder metallurgy (PM). The availability of products from both of these established processes gives users many options in selecting a material to satisfy their specific application requirements. Mill products available from either process include forging billets, bar, rod, sheet, plate and foil.
