摘要： A mixture for a powder metallurgy product, including iron powder, graphite powder and copper (Cu) of about 3.0 to about 5.0 weight percent. Iron powder includes iron grains which contain MnS therein. The mixture contains the MnS of about 0.65 to about 1.40 weight percent. The graphite powder is contained in the mixture such that an amount of carbon (C) in the powder metallurgy product is about 0.3 to about 0.7 weight percent. An amount (wt % C) of the carbon and an amount (wt % Cu) of the copper is determined to obtain a target fatigue strength FS (MPa) and a target hardness HR (HRB) based on a relation FS=66.63×(wt % C)+22.61×(wt % Cu)+280.84 HR=22.96×(wt % C)+2.99×(wt % Cu)+78.91.

摘要： In a composite light alloy member in which a reinforcing portion is bonded or joined to a member body is formed of a reinforcing material and a light alloy matrix filled in said reinforcing material, the reinforcing material is a heat resistant continuous-pore type element having a porosity of 90% or less and an average diameter of pores of 100 .mu.m or less. The reinforcing material may be a metal or ceramic sinter that is preformed and cast into the composite light alloy member.
