Abstract: The porous TiC/FeAl composites were fabricated by using carbamide as apace-holders via self-propagating high-temperature synthesis (SHS). The effects of Ti-C contents (mass fraction:15wt%-35wt%) on the pore structures and compressive behaviors of the porous TiC/FeAl composites were investigated. When Ti-C content is not more than 25wt%, the porous TiC/FeAl composites exhibit composite pore structures composed of millimeter pores and micro pores dispersed in pore walls. The interconnected millimeter pores originate from the volatilization of carbamide particles and the migration of liquid phases, while the micro pores are formed during the SHS process of the Fe-Al-Ti-C powders, the pore size (10-50 μm) of micro pores increases with increasing Ti-C content. Depending on the volume fraction of the carbamide, the porosity of the porous TiC/FeAl composites can be controlled in a range of 56.64%-85.35%. When Ti-C mass fraction is not more than 25wt%, the compressive strength of porous TiC/FeAl composites increases with increasing Ti-C content. When Ti-C mass fraction is higher than 25wt%, the morphology of micro pores becomes very irregular, and the compressive strength decreases. As the porosity is about 64.3%, the compressive strengths of porous Fe-Al and porous TiC/FeAl composite with 25wt% Ti-C are 20.03 MPa and 66.68 MPa, corresponding strains are 4.77% and 8.21%, respectively. Furthermore, the compressive behavior of porous TiC/FeAl composites can be understood by the Gibson-Ashby model.
