Sintered properties of 409L powder compacts influenced by metal powder additives
AbstractSintering of powder compacts, prepared by admixing of 409L powder with 2-6 wt.% of copper and nickel powders was investigated. It was observed thatthe strength of the 409L-Cu specimens increased with increasing Cu content. In contrast, sintered densityand elongation decreased with increasing Cu content due to swelling effect. When 2 wt.% of Ni powders were added, sintered density and strengths were maximized. When Ni contents higher than 2 wt.% , the decrease of sintered density and strengths were attributed to the number of pores left by the original sites of Ni powder particles.
