摘要： A process for producing a precision metal part of a sintered body by powder molding comprises using a metal powder of which the oxygen content and the hydrogen reduction loss are controlled to 0.5-6 wt. % and 1-7 wt. %, respectively. The sintered body has a high density near the theoretical density and is excellent in dimensional accuracy. The molding is facilitated, and the process is simple.

摘要： This manufacturing method of a powder injection molded part includes the steps of using a binder composition containing at least 2 kinds of thermoplastic binder components having an evaporation temperature higher than the injection molding temperature and a different evaporation initiating temperature from each other, elevating the temperature of a molded body above the evaporation initiating temperature of the binder component having the lowest evaporation initiating temperature rapidly, removing the binder component having the lowest evaporation initiating temperature from the molded body by holding this temperature, and thereafter, removing all binder components by elevating up to a temperature not lower than the evaporation initiating temperature of the binder component having the highest evaporation initiating temperature. By this method, the form unstability of final parts, which is a problem of the prior art, is resolved, dimensional accuracy is satisfied, and it is possible to shorten debinding times.

摘要： A valve spring retainer for a valve operating mechanism for an internal combustion engine comprises a matrix formed from a quenched and solidified aluminum alloy powder, and a hard grain dispersed in said matrix. The hard grain is at least one selected from the group consisting of grains of Al.sub.2 O.sub.3, SiC, Si.sub.3 N.sub.4, ZrO.sub.2, SiO.sub.2, TiO.sub.2, Al.sub.2 O.sub.3 -SiO.sub.2 and metal Si. The amount of hard grain added is in a range of 0.5% to 20% by weight, and the area rate of said hard grain is in a range of from 1% to 6%.
