Co–Cr–Mo atomized powders containing 0.05 wt.% C were sintered at temperatures above 900 °C for 1 h and then rapidly cooled to room temperature. As a result, various amounts of athermal ε-martensite were produced which increased with increasing sintering temperatures (from 30 vol.% at 950 °C to 70 v...
