Abstract

The invention relates to a production method for particle reinforced aluminum matrix composite ingots. The method comprises the steps of naturally stacking small spherical porous bodies in a casting die inner cavity, adopting a vacuum-pressure infiltration molten metal method to produce ingot blank, enabling the composite ingot blank to be subjected to thermal plasticity such as extrusion, rolling or forging, and obtaining particle reinforced metal matrix composite products. Not only is the production method simple in production process and low in production cost, but also the products have higher performance than products produced through a powder method.

Description

technical field [0001] A method for producing particle-reinforced aluminum-based composite ingots, which uses a liquid-phase method of vacuum-pressure infiltration to produce a cast slab from a packed bed of pellet preforms, especially for casting particle-reinforced aluminum-based composites for secondary processing. A method of manufacturing a composite blank. Background technique [0002] Metal matrix composites are known as the materials of the 21st century, and they are new materials that meet the comprehensive requirements of the rapid development of the information age. Metal matrix composites have the characteristics of other groups of raw materials on the basis of giving full play to the excellent performance of the matrix material, especially it can give full play to the synergistic effect of each component material. Particle-reinforced Al-matrix composites are a new high-tech material with the most extensive application prospects in metal matrix composites (MMC)....
