COMPOSITE SINTERED COMPACT, AND PRODUCTION METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To sufficiently improve the joining strength of a composite sintered compact by suppressing the peeling of boundaries caused by sintering shrinkage generated only in either member side in the initial stage of sintering. SOLUTION: The composite sintered compact consists of a first member 10 obtained by sintering first raw material powder consisting mainly of first metal powder 1 and a second member 20 obtained by sintering second raw material powder consisting mainly of second metal powder 2 having a sintering starting temperature higher than that of the first metal powder 1, and both members are integrally joined by sintering. The first metal powder 1 is incorporated into the second member 20 within a range of such a blending amount that the properties of the second member 20 to be required can be secured.
