【Abstract】 High carbon and high vanadium high-speed steel/45 steel bimetal composite material was fabricated by improved inlayed-casting.The morphology and structure of composite material bonding interface under different technological parameters was studied.The results show the well-bonded interface can be gained under proper technologic parameters,the main bonding pattern of bimetal composite material is diffused bonding,and the proportion of cast-inlayed and holding time have obvious effect on interface structure of composite material.更多还原
