Abstract
The presence of non-reactive hard particles (Al2O3) causes some effects on P/M processing of sintered Fe materials. With constant compacting pressure and sintering conditions, particle size and quantity of Al2O3 particles caused reduction of green and sintered densities. Tensile strengths, elongation and hardness of the sintered material were maximum when 2 wt.% of Al2O3 particles with particle size between 20-32 um was added. The presence of Al2O3 particles may reduce sinterability of the Fe powder.
