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。 MoSi2-SiCp composite materials were prepared by pressureless reaction sintering method. The results show that it is difficult to obtain compact MoSi2-SiCp composite materials by direct reaction of elemental powders Mo, Si with Si, C powder or SiC powder. However, the compact MoSi2-SiCp Complex materials. At the same time, the strength and resistivity of MoSi2-SiCp composite materials with different SiC content were measured and analyzed. The highest intensity was 157MPa and the resistivity increased with the increase of SiC content.
