The analyses for Sanhui TZM which are in accordance with the ASTM-specification B384, 385 and 386 for the molybdenum alloy 364.
By precipitation of fine dispersoids the alloying elements give rise to both solid solution hardening and dispersion hardening. By forming finely dispersed oxides and carbides they prevent the undesirable grain growth which occurs in pure molybdenum at high temperatures.
Therefore TZM possesses the following advantages over pure molybdenum:
1.higher recrystallization temperature;
2.better high-temperature strength
3.reduced tendency to heat deformation
4.better weldability
5.reduced tendency to embrittlement.
TZM has similar machining and forming conditions as molybdenum. Furthermore, TZM as well as molybdenum possesses high resistance to different molten metals and a good thermal conductivity.
