Preserved Fulltext
It has been known B is the most effective sintering enhancer for stainless steel powders. But at the same time, a considerable grain growth was often seen in the sintered compacts containing B. In order to obtain the sintered compacts with high densities and fine-grain structures, 0.2-1.4 mass%A1203 fine powders were mixed with SUS316L water atomized steel powder, in addition to 0.4 mass% B powders. These mixed powders were compacted and sintered in H2 atmosphere at 1232•'1252•Ž for 1 hr.
