HWM-25 alloy (25% tungsten, 1% hafnium, 0.07% carbon) offers high-temperature strength greater than that of carbide-strengthened molybdenum, but it has not found wide commercial application .
Because of the added cost of tungsten and the expense of processing the material.Dispersion-strengthened alloys rely exclusively on powder metallurgy manufacturing techniques.
This allows the production of fine stable dispersions of second phases that stabilize the wrought structure against recrystallization, resulting in a material having improved high-temperature creep strength as compared to pure molybdenum.
