Abstract
PURPOSE:To produce a high toughness Al alloy material having excellent strength and wear resistance by atomizing the hypereutectic Al-Si alloy melted in vacuo, blowing the same on a cooled body and subjecting the atomized grains to fining or quench solidifying. CONSTITUTION:The hypereutectic Al-Si alloy contg., by weight, >=21% Si and furthermore contg. at need 0.5-5% Cu or 0.05-5% Mg is melted, is atomized by a compressed gas in a vacuum vessel while introducing an inert gas thereto at need and is blown on the cooled body. At this time, the size of the atomized grains is at least regulated to <=200mum or the cooling ratio at the time of solidifying is regulated to >=100 deg.C/sec. By this method, the titled material having >=0.1mm thickness in which >=25% areal ratio of Si crystals having <=20mum grain size are present in the matrix of a homogeneous solid solution phase is obtd. Said alloy material has excellent strength, toughness, wear resistance, seizing resistance, etc., and has good adhesion with the matrix as well.
