Abstract:The dense TiC-Fe cermets were produced by self-propagating high temperature synthesis and pseudo-hot isostatic pressing(SHS/PHIP). The influence of Fe content on the combustion temperature, combustion velocity, density and microstructure of products was studied. The composition and microstructure of the product were analyzed. The results showed that the cermet consists of quasi-spherical TiC particles and Febinder phases. A thin diffusion layer was found between Fe binder phase and TiC particle. In the range of 10%~20% Fe content, the combustion temperature and velocity decrease more slowly than the other contributions.
Key words: SHS/PHIP; TiC-Fe cermet; microstructure; Fe-binder phase
