Abstract
A method to produce a sintered metal with an improved abrasion resistance and durability, and a rotary compressor flange produced by use of the method. The sintered metal is produced by kneading metal powder, pressure molding the kneaded powder, and sintering the molded powder. The sintered metal is further produced by subzero treating the sintered metal powder for a predetermined time and tempering the resulting sintered metal powder under a predetermined compression residual stress.
