摘要：
Fe based prealloyed powders were manufactured by co-precipitation method. The mechanical properties of samples sintered at different temperatures were tested. Alloy's structure formed during co-precipitation process was studied by XRD and the morphology was observed by SEM. The results show that the sintering temperature should be less than 900 and the mechanical properties of the alloys are the best when sintered at 850. The samples sintered at 850 have the uniform grain size and best mechanical retention of matrix applied to diamond. ©, 2015, Chinese Ceramic Society. All right reserved.
