摘要：

The effect of particle shape on the angle of internal friction of fine powders was investigated by triaxial compression test. Angular stainless steel powder was processed toward increasing sphericity by a rotational impact-type surface modification apparatus. The angle of internal friction was found to increase with increasing angularity of particles and decreasing initial voidage of the specimen owing to increase in the interlocking effect.
