中文摘要:通过分析不同稀土La添加量对铁基胎体烧结性能的影响，指出在本试验使用预合金粉末和烧结条件下，当La添加量为0.1%时，胎体材料的综合力学性能最好。此外，适量的稀土La加入铁基胎体粉末后可以改善粉末分布的均匀性，提高金属胎体对金刚石的包镶能力。

Influence of La Addition on the Properties of Pre-alloyed Fe-based Matrix Material
Abstract:Under some fixed sintering temperatures，the effects on the sintering properties and microstructures of Re(La) content in Fe-based matrix were studied. The optimum mechanical properties of Fe-based matrix were attained at the La content of 0.1%. The distribution of matrix and the retention of diamond in matrix were also improved with proper La addition.
