Information

The common preparation methods of TZM alloy (molybdenum zirconium titanium alloy) are: arc melting-casting method and powder metallurgy technology. TZM alloy rod arc melting-casting method is to use electric arc to melt pure molybdenum and add a certain amount of alloying elements such as Ti and Zr according to the weight percentage, and then use conventional casting methods to obtain TZM alloy (molybdenum zirconium titanium alloy); powder metallurgy is unique The chemical composition and mechanical and physical properties of the product, and these properties cannot be obtained by traditional melting and casting methods. It uses high-purity molybdenum powder, TiH2 powder, ZrH2 powder and graphite powder to be uniformly mixed in proportions, and then formed by cold isostatic pressing, and then sintered at a high temperature in a protective atmosphere to obtain a TZM blank. The billet is then subjected to 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 obtain the TZM finished material. The rolling (forging) process of the blank and the subsequent heat treatment have a great influence on the properties, anisotropy and texture of the material. The use of powder metallurgy can save large equipment such as vacuum consumable electric arc furnaces, large extruders and forging hammers, and corresponding high-temperature heating furnaces, simplifying the process, shortening the production cycle, reducing energy consumption, and doubling the production capacity and yield rate. , So the cost is greatly reduced. TZM alloy (molybdenum-zirconium-titanium alloy) is usually prepared into bars and plates. Powder metallurgy can save large equipment such as vacuum consumable electric arc furnaces, large extruders and forging hammers, and corresponding high-temperature heating furnaces, simplifying procedures, shortening production cycles, reducing consumption, increasing production capacity and yield, and therefore cost Greatly reduced.
