The effect of 1200 ℃ heat treatment and 40%~60% hot deformation at 1050~950℃ on diameters and volume fraction of carbide in 3 mm cast-strip of high speed steel M2(W6Mo5Cr4V2)using Gleeble 1500D auto thermo- simulation machine have been studied by quantitative metallographic examination. The studied results showed that the car bide size in steel M2 was fined and distribution of carbide was improved in cast-strip by high temperature heat treatment and hot deformation
and 1200 ℃ 40 min heat treatment + 50% hot deformation was available to get fine carbide(0.96 μm) and homogeneous distribution.
