Research Progress in Particle Reinforced Copper Matrix Composites Prepared by In-Situ Reaction Method
摘要
Abstract
Granular reinforced copper matrix composites can combine high strength,thermal stability,wear resistance,and excellent electrical and thermal conductivity,with evenly dispersion particles.They are the key materials for various electrical and thermal con-ductivity components in nuclear reactors,aircraft and high-end equipment,and play an irreplaceable role in many important fields such as nuclear power,aviation,transportation and military.The in-situ preparation method is a technology that generates one or several ce-ramic reinforcements in situ through a chemical reaction in the metal matrix at a certain temperature.In-situ reaction preparation of par-ticle-reinforced copper-based composites has two important problems to be solved urgently:one is the problem of agglomeration of the reinforcing phase,and the other is the problem of the size control of the reinforcing phase.This article summarized several commonly used in-situ reaction methods for preparing dispersion strengthened copper matrix composites,and compared the advantages,disadvan-tages,characteristics,and technical difficulties of these methods.The influence of in-situ reaction method on the size and distribution of particles in copper matrix composites was also reviewed.The influence of different parameters of in-situ reaction on the mechanics and comprehensive properties of copper matrix composites was analyzed.Based on the principle of nucleation and growth of reinforced phase particles,a process plan was proposed to promote the enhancement of fine dispersed particles in the reinforced phase.关键词
