【摘要】 采用特种铸造工艺,制成了一种含40%WC的新型WC/钢硬质复合材料。对这种被认为不能锻造的材料进行了锻造研究。结果表明:只要正确掌握锻造工艺,不仅可以锻造改形,而且还改善了材料内部的不良组织结构,使其韧性明显提高。更多还原

【Abstract】 A new kind of WC/steel hard composite material was made by special casting.Forging of this new matirial which was thought not to be forged was studied.The results show that as long as master correctly forging technological process,this hard and fragile matirial may be not only charged its shape but also get better its bed microstructure by forging and as a result its toughness increased.更多还原
