摘要:The effect of M additions on the microstructure and mechanical properties of TiC-based cermet produced by li oquid sintering method of powder metallurgy was investigated. The Mo content was varied between 0 and 0.8 wt.%, in 0.2wt.% increments. These flaws drastically decreased with increasing Mo content. As in conventionally produced materials, Mo was found preferentially on the carbide phase. Mo-rich regions due to incomplete dissolution of large Mo agglomerates were observed.
