IRON-BASE MIXED POWDERS AND PROCESSES FOR PRODUCTION OF IRON-BASE POWDER COMPACTS AND SINTERED IRON-BASE POWDER COMPACTS

Document Type and Number:

WIPO Patent Application WO/2007/105429

Kind Code:

A1

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°C and the sintered compact made from the powder is favorably excellent in machinability.
