摘要

Mg2Si颗粒具有熔点高、硬度高、密度低和热膨胀系数小等特点,其作为增强体与铝基体结合性能良好,使得Al-Mg2Si合金材料拥有良好的力学性能。过共晶Al-Mg2Si合金材料在拥有低密度特点的同时具备了优异的耐磨性能,成为了汽车、摩托车发动机活塞和气缸盖生产的可选材料。本文介绍了Al-Mg2Si合金材料的发展现状,重点综述了过共晶Al-Mg2Si合金材料的制备技术、变质机制和合金元素的变质作用。

Abstract:

Mg2Si particles are characterized by high melting point, high hardness, low density and small coefficient of thermal expansion, etc. Due to their good bonding performance with aluminum matrix as the reinforcement, Al-Mg2Si alloy material possesses good mechanical properties. Al-Mg2Si hypereutectic alloy material has excellent wear resistance while possessing low density characteristics, and it has become an optional material for piston and cylinder head production of automobile and motorcycle engines. In this paper, the development status of Al-Mg2Si alloy material is introduced, and the preparation technology, metamorphism mechanism and the metamorphism of alloying elements of Al-Mg2Si hypereutectic alloy material are mainly reviewed.
