Preparation process for quasi-crystal particles reinforced aluminum base composite material

Abstract

A process for preparing pseudo crystal granule reinforced magnesium group composite material, wherein the process for preparing AlCuFe pseudo crystal particles comprises the steps of, preparing powder, obtaining 20-100 um pseudo crystal particles after screening, with its composition being Al, Cu, Fe, after base stock melting, charging reinforced particles into alloy fondant for full mixing, depositing on the base stock along with the atomization alloy solid-liquid mixing at the atomizing action, finally the granule reinforced magnesium group composite material with even reinforced particle size distribution and fine base metal crystal grains can be prepared.

Description

technical field [0001] The invention relates to a preparation process of quasi-crystal particle-reinforced aluminum-based composite material, in particular to a preparation process of agitated jet co-deposited quasi-crystalline particle-reinforced aluminum-based composite material, which belongs to the field of aluminum-based composite material. Background technique [0002] Particle-reinforced aluminum matrix composites have been widely valued due to their high specific strength, high specific modulus, low density, and good heat resistance. However, the reinforcing phase in composite materials is mostly ceramic particles such as Al 2 o 3 , SiC, Si 3 N 4 , TiC, B 4 C, AlN, etc., these substances are prone to agglomeration due to their poor wettability with the molten matrix metal during the preparation of composite materials, and due to the difference in thermal expansion coefficients between ceramic particles and the matrix metal, they are produced during casting and sol...
