Abstract

An iron-base mixed powder for powder metallurgy which comprises an iron-base powder and at least one member selected from between talc and steatite and preferably further contains a metal soap.This mixed powder does not produce adverse effect on furnace atmosphere in sintering a compact of the powder and exhibits excellent compactibility even in a low-temperature region of below 100 DEG C and the sintered compact made from the powder is favorably excellent in machinability.

Description

technical field

[0001] The present invention relates to an iron-based powder mixture in which a lubricant and, if necessary, an alloying powder are mixed in an iron-based powder. The iron-based mixed powder of the present invention is also suitable for powder metallurgy (powder metallurgy), especially suitable for compaction in the temperature range from normal temperature to less than 100°C.

[0002] The present invention also relates to mixed powders for powder metallurgy suitable for the manufacture of high-strength sintered parts for automobiles.

[0003] In addition, the present invention also relates to a method for manufacturing an iron-based powder compacted body using the iron-based mixed powder as a raw material, and a method for manufacturing an iron-based powder sintered body (sintered body) using the iron-based powder compact as a raw material method. Background technique

[0004] The iron-based mixed powder for powder metallurgy is usually produced by adding ...
