用不同比例的Fe和Ni部分代替WC-8Co合金中的粘结剂Co, 再添加微量的碳粉和稀土氧化物Y2O3制得WC-8(Fe, Co, Ni)RE硬质合金, 测试了其物理机械性能, 研究了粘结剂各种成分及烧结温度、烧结气氛对硬质合金性能的影响. 在一定的烧结工艺下, 以Fe和Ni部分代替Co所制得的WC-8(Fe, Co, Ni)RE硬质合金, 其性能可以达到甚至超过YG8的标准, 同时对影响WC-8(Fe, Co, Ni)RE硬质合金性能的一些因素进行了讨论.

Measurements of magnetic susceptibility in mechanically alloyed Fe-Ni Invar alloys were taken under pressures up to 7.5GPa. The rate of decrease in the Curie temperature for 700℃ annealed specimen was larger than that annealed at 1000℃. This result can be explained by considering the fact that the width of the concentration fluctuation becomes larger in the specimen annealed at lower temperature.
