摘    要:采用无压反应烧结方法制备了MOSi2-SiCp复相材料。结果表明:直接采用元素粉Mo,Si与Si,C粉或SiC粉反应,较难制得致密的MOSi2-SiCp复相材料;而采用MoSi2合金粉同Si,C反应可获得致密的MOSi2-SiCp复相材料。同时对不同SiC含量的MOSi2-SiCp复相材料的强度和电阻率进行了测定分析,得到强度最高值为157MPa,电阻率随SiC含量的增加而增加。

关 键 词:MOSi2-SiCp 复相材料 无压反应烧结 制备 性能

Abstract:A MoSi2 SiC p composite was prepared by a reactive sintering without pressure. The results showed that a dense MoSi2 SiC p composite can not be made directly from the molybdenum and silicon powders reacted with carbon powder, but from the alloyed MoSi2 powder reacted with silicon and carbon powders. The strength and electrical resistivity of MoSi2 SiC p composite with various silicon carbide contents were measured and analysed at the same time. The results showed that the highest strength was 157 MPa and the electrical resistivity increased with the increase of SiC content.
Keywords:MoSi2 SiCp  composite  reactive sintering without pressure
