THE EFFECT OF PARTICLE SIZE OF IRON POWDER ON THE PHYSICAL PROPERTIES OF THE POWDER AND OF IRON POWDER COMPACTS

摘要

This report presents the results of a series of tests which were run to determine the effect of particle size on the physical properties of iron powders and compacts prepared therefrom by standard powder metallurgical techniques. Lots from four different makes of iron powder, two of the electrolytic type and two of the reduced type, were subdivided into frac¬tions of increasing fineness by sieving and air classification. The tests were applied to the original powders as well as to their fractions.
