| Abstract: | In this paper, densified TiC 30wt%Fe cermet was produced by self propergating high temperature synthsis and pseudo hot isostatic pressing(SHS/PHIP) The composition and microstructure of the product were analysed A formation mechanism for the cermet made by SHS/PHIP was proposed The results show that the cermet consisted of quasi sphere TiC particles and Fe binder phase A thin diffused layer was found between Fe and TiC |
