TZM alloy is the most widely used molybdenum alloys. It has many excellent properties, such as high melting point, high strength, high temperature and corrosion resistance and so on. TZM alloy refers to containing 0.5% Ti, 0.08% Zr and 0.02% C's molybdenum base alloy. Compared with pure molybdenum, TZM alloy has higher temperature and higher temperature strength. Further recrystallization temperature of TZM alloy is higher than pure molybdenum. TZM alloy starting recrystallization temperature and ending recrystallization temperature improved 500 ℃ and 450 ℃ than pure molybdenum. TZM alloy performance is higher than pure molybdenum mainly because added element occurs second phase strengthening in the alloy, leading alloy performance improved. Add a small amount of metal element in molybdenum matrix so that the mechanical properties at room and elevated temperatures have been greatly improved, but also to expand the application fields of the alloy.
TZM alloy elongation, elastic modulus, yield strength, tensile strength and fracture toughness property and other mechanical properties are better than pure molybdenum, and it helps to manufacture. Therefore TZM alloy can be processed into different shapes, used in different fields. In addition, TZM alloy has good weldability can be welded with other materials to make titanium zirconium molybdenum customized (TZM customized).
Common TZM a customized product includes TZM nut, TZM screw, TZM nozzle, TZM hot runner and so on. TZM alloy has good workability and weldability, so China Tungsten Online (Xiamen) Manu. & Sales Corp can produce different TZM customized according to customer requirements and application areas to meet different customer needs.
TZM customized production processes are as follows: uniformly mixed high-purity molybdenum powder with TiH2 powder, ZrH2 powder and graphite powder in proportion, pressed by cold isostatic pressing, sintered at high temperature with protective atmosphere protection, obtain TZM blanks. TZM Blank processed hot-rolled (hot forging), high-temperature annealing, warn rolling (warn forging), warm annealing to relief stress to produce TZM alloy. Finally, after subsequent process obtain TZM customized.
