Description

Ball milling of ferritic stainless steel-4 vol% Al2O3 powder was carried out for the duration up to 222 ks. Attritor milling of ferritic stainless steel-6 vol% Al2O3 were also carried out for the duration up to 32.4 ks. The characterization of the milled powders were performed. The sintering of ball milled powders was carried out at 1623 K for 10.8 ks in hydrogen. The premix of as received stainless steel powder and the attritor milled powder was also sintered at 1623 K for 3.6 ks in hydrogen. The results showed that an optimum ball milling period in between 58 and 173 ks was required to achieve better sintered properties. The attritor milling was more effective in grinding the powders as compared to ball milling, and the sinterability was also higher for such powders. (author)
