    TZM Molybdenum Alloy Springs are helix shaped springs that can store and release mechanical energy, absorb shock, or maintain a force between contacting surfaces. TZM Molybdenum Alloy Spring is available as disc, granules, ingot, pellets, pieces, powder, rod, tube, sputtering target and in numerous other forms. The resultant alloys have mechanical properties similar to other high temperature molybdenum alloys while possessing a greatly enhanced resistance to oxidation at high temperature.

    TZM alloy abstract Molybdenum powders were high-energy ball milled for 3, 6, 9 and 12 h respectively, using two ball milling methods: (1) dry milled in vacuum and (2) wet milled in mixed solution of ethanol-polyethylene glycol. The effect of high-energy ball milling on relative density of titanium-zirconium-molybdenum (TZM) alloy was investigated. TZM alloy (Titanium Zirconium Molybdenum) at high temperatures compared to pure molybdenum has a higher recrystallization temperature and high strength and hardness. It also has a sufficient extension. Because dispersed in the matrix of the composite molybdenum carbide circular arc, which has excellent mechanical properties.
