Effects of Admixed Titanium on Densification of 316L Stainless Steel Powder during Sintering

Effects of Admixed Titanium on Densification of 316L Stainless Steel Powder during Sintering

Effects of admixed titanium on powder water atomized (PWA) and powder gas atomized (PGA) 316L stainless steel (SS) have been investigated in terms of densification. PGA and PWA powders, having different shapes and sizes, were cold pressed and sintered in argon atmosphere at 1300°C. The admixed tita...

PGA and PWA powders, having different shapes and sizes, were cold pressed and sintered in argon atmosphere at 1300°C. The admixed titanium compacts of PGA and PWA have shown significant effect on densification through formation of intermetallic compound and reducing porosity during sintering process. PWA, having particle size 8 μm, blended with 1wt% titanium has exhibited higher sintered density and shrinkage as compared to gas atomized powder compacts. Improved densification of titanium blended PGA and PWA 316L SS at sintering temperature 1300°C is probably due to enhanced diffusion kinetics resulting from stresses induced by concentration gradient in powder compacts. http://dx.doi.org/10.1051/matecconf/20141304026
