Abstract

Aim\ To select the heat treatment technology for the alloy D9158. Methods\ The effect of microstructure on mechanical properties of the alloy after ageing at different times and under different temperatures has been inverstigated by means of mechanical properties test

X ray diffraction and SEM

etc. Results\ Fine and disperse M\-6C and Laves phase in basic phase γ are formed through different solutions and ageing processes. Conclusion\ The technology (1 160 ℃×1.5 h

W.C.+750 ℃×5 h

A.C.)is suitable

when the alloy is to be used for heat extruding dies.
