| Abstract: | Precipitation and microstructure of WC phase from multiple carbides in heat treated Steel-bonded carbide TLMW50 were investigated by SEM. The results showed that the precipitation of WC phase from Fe3W3C,Fe2W2C phase was observed in TLMW50 as-quenched in 1100℃, the triangular or rhombie WC phase precipitates were randomly distributed in Fe3W3C,F2W2C phase particles. The precipitation of WC phase was propitious to increase the rigidity of the Steel-bonded carbide TLWM50. The XRD diffracting results showed that The numbers of WC phase precipitates decreased with the increasing of temper temperature from 150℃- 250℃. |
