Effects of Sintering Temperature on the Microstructure and Properties of (Ti, W, Mo)C-Ni Cermet

摘要

摘要: 通过碳热还原法制备(Ti, W, Mo)C预合金化固溶体粉末, 采用粉末冶金法制备(Ti, W, Mo)C-Ni金属陶瓷, 研究了烧结温度对金属陶瓷致密性、组织与性能的影响。结果表明: 在1 410~1 470 ℃范围内, 随烧结温度提高, 金属陶瓷的硬度提高, 致密性先提高后略下降; 在1 450 ℃时制备的金属陶瓷晶粒细小、组织均匀致密, 呈现最佳综合力学性能, 横向断裂强度为1 751 MPa, 硬度为91.3 HRA。

Abstract: (Ti, W, Mo)C pre-alloyed solid solution powders were produced by carbothermal reduction method and (Ti, W, Mo)C-Ni cermet was prepared by powder metallurgy method. The effects of sintering temperature on compactness, microstructure and properties of cermet were studied. The results show that in the range of 1 410-1 470 ℃, the compactness of cermet gradually improved and then decreased slightly, and the hardness rose, with the increase of sintering temperature. At 1 450 ℃, the cermet with homogeneous compact microstructure and fine grains, had the best comprehensive mechanical properties, a transverse rupture strength of 1 751 MPa and a hardness of 91.3 HRA.
