Abstract

The presence of non-reactive (Al2O3) and reactive (SiC) hard particles affected properties of sintered Fe-base composites. With the same compacting and sintering conditions, addition of Al2O3 particles caused reduction of sintered densities. Tensile strengths, elongation and hardness of the sintered Fe-Al2O3 materials decreased with increasing Al2O3 particle amounts. The presence of Al2O3 particles prohibited compacting and sintering processes of the Fe powder. In contrast, addition of SiC particles resulted in reaction between Fe and SiC particles. Sintered density of the sintered Fe-SiC composites was significantly lower than that of the sintered Fe-Al2O3 materials. However, tensile strengths and hardness, except elongation, of the sintered Fe-SiC composites were significantly improved.
