Grain refining manner and nitrogen addition Co Cr Mo alloy of nitrogen addition Co Cr Mo alloy

摘要

Cr: 26 - 35 weight %, Mo: 2 - 8 weight %, N: In order to obtain uniform minute grain structure with just heat treatment without administering processing like the hot forging which utilizes recrystallization 0.1 - 0.3 weight %, at the time of producing the nitrogen addition Co Cr Mo alloy which consists of remainder Co, the solution treatment after doing, fixed time containment in 670 - the 830 , being something which does the adverse change voice treatment where it does the homoiothermal aging treatment which forms the mixed phase system which consists of with phase and the Cr nitride, after the cooling, re-heats to the temperature area of 870 - the 1100 , from mixed phase system of phase and the Cr nitride adverse change voice it can point in gamma-phase haploidCertain.
