Abstract

The present invention is a simple production process of hard phase strengthened metal-base composite material with high efficiency, low power consumption and easy-to-control product quality. After the base metal is smelted or the metal grain is smelted in a crystallizer, the smelted metal and strengthening hard phase material are fast crystallized through electromagnetic field stirring and supersonic vibration inside a water cooled crystallizer to form the produce. Thus formed composite material has two homogeneous mixed and well combined phase, large regulatar system region, fine crystal structure and improved and consistent performance.

Description

technical field [0001] The invention relates to a composite material production process, in particular to a hard phase reinforced metal matrix composite material production process. Background technique [0002] In the literature "Cemented Carbide" magazine (August 1993, Volume 10, No. 3, Page 169-173), "Hard Particle Steel Matrix Composite Material" was reported, and MMC was disclosed in the report. s The production process of metal matrix composites (Metal Matrix Composites), the commonly used production process is powder metallurgy sintering method, that is, the tough metal matrix powder and short fibers, whiskers and hard insoluble compound particles are prepared and mixed according to a predetermined ratio. Pressed, sintered. The product produced by this process has poor performance consistency, weak two-phase bonding force, easy to generate crack propagation on the two-phase interface, large porosity, and poor compactness, which reduces t...
