摘要
在铁镍部分代钴的基础上，实验添加不同量稀土，结果表明，加入适量稀土可使合金的抗弯强度的提高最大幅度达５．８％；硬度增加０．２～２．０ＨＲＡ。同时，对稀土强化铁镍代钴硬质合金的机理进行了初步探讨。
Abstract The cemented carbides
in which Co is replaced by Ni,Fe and Re is added are studied.The results shows that its bending
strength is improved in some extent,its maximum improving amplitude is 6.9%,its hardness is
improved 0.5～2.0HRA.The strengthening mechanism han been discussed.
