Abstract

PURPOSE: To produce the titled member by subjecting the Al alloy powder having the specific compsn. including Si, Cu and Mg to green compacting, forging the same directly under the melting point, thereafter quenching said powders and furthermore subjecting the same to a heat treatment.
CONSTITUTION: The Al-Si alloy powder contg., by weight, 30W50% Si, 1W5% Cu, 0.5W5% Mg and the balance Al with inevitable impurities is produced by a quenching solidifying method. Said alloy powder is subjected to green compacting, hot forging at about 450W520°C directly under the melting point and thereafter quenching. In this way, high density is provided to said green compact; primary phase Si therein is fined; and shaping is applied to the green compact. Said green compact is thereafter subjected to a precipitation hardening heat treatment to form a structure where primary phase Si having 2W15μm average grain size and precipitated intermetallic compounds having ≤1μm average grain size are uniformly dispersed into a matrix. The high strength wear resistant Al-Si alloy forged member having about 14W12×10-6/°C thermal expansion coefficient is thus obtd.
