The composite with steel-bonded cemented hard alloy TLMW50 cladding and carbon steel substrate was fabricated by liquid sintering process successfully.The effects of the heat treatment with being quenched at 1050℃ or 1100℃ and tempered at 150℃,200℃,250℃ on microstructure and morphology of the composite were researched by SEM,XRD.The results show that this six heat treatment processes make the bonding phase of the steel-bonded cemented hard alloy TLMW50 cladding microstructure transitted from pearlite to tem...
