ABSTRACT:
A mixed powder for powder metallurgy comprising a Fe powder and an alloy powder mixed together in which the mean particle size and the solidus line temperature of the alloy powder and the amount of the liquid phase formed during sintering are so defined as to attain most suitable sintering behavior, that is, the mean particle size of the alloy powder is smaller than 20 .mu.m, the solidus line temperature of the alloy powder is set to higher than 950.degree. C. and lower than 1300.degree. C. and the amount of the liquid phase formed during sintering is more than 20%. A sintered product having desired properties can be obtained by using the mixed powder described above.
