heal.abstractDifferent combinations of critical and subcritical heat treatments variously modify the initial as cast microstructure of high chromium white cast irons leading to secondary carbide precipitation of different extent and nature. Destabilisation (critical heat treatment) of austenite at 970 degrees C for 2.5 h followed by annealing (subcritical heat treatment) at 600 degrees C for 13 h results in massive precipitation of M(23)C(6) carbide particles along with spheroidised M(7)C(3). The reversed order of heat treatments leads to extensive precipitation of M(7)C(3) secondary carbide particles. Mo has a favouring effect on the hardness of the microstructures containing pearlite by limiting pearlite formation. The gradual increase in the alloying additions, C and Cr, increases the hardness of the materials at the different treatment states by inducing carbide precipitation. The increase in the Si content leads to the opposite effect by favouring pearlite formation.en
