The particle size of the starting powder, like the grain size of sintered specimens, does not have a pronounced effect on the mechanical properties of sintered iron because the effective length or a slip plane is determined by the size of the smaller

1. Curves of percentage elongation plotted against sintering temperature exhibit two extreme points, namely, a maximum at 850° C and a minimum at 900° C. When the sintering temperature is raised above 900° C, the elongation increases. 2. The prese
