Abstract

In this study, stainless steel 316L bimodal powder sintering was studied. The sintering has been found to be a two stage process. The bimodal powders at first stage are sintering at higher temperatures and the process proceeds with higher rate than for nanoparticles. The method of the dilatometry data analysis has been developed for the first time. It enabled the determination of the sintering process parameters, specifically the process activation energy. The analysis has showed the change of the dominating mass transfer mechanisms of the sintering process depends on heating rate.
