Embodiment Construction

[0010] In order to enable those skilled in the art to better understand the technical solution of the present invention, and to make the above-mentioned purpose, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with examples.

[0011] The processing technology described in the present invention can be applied not only to continuous, long-fiber-reinforced, but also to short-fiber, particle or whisker-reinforced metal matrix composite materials. The powder wood metallurgy process of short fibers, particles or whiskers reinforced metal matrix composites is mainly divided into two parts. First, the reinforcing fibers (short fibers, particles or whiskers) are mixed with metal powder evenly, mostly by mechanical mixing; then Carry out packaging, degassing, and then perform hot isostatic pressing to improve the compactness of the composite material. Specifically, in the embo...

Abstract

The invention provides a processing technology for a metal composite material. The metal composite material comprises reinforcing fibers and a substrate. The processing technology comprises the following steps of: uniformly mixing the reinforcing fibers and substrate powder; and packaging, degassing, and performing hot isostatic pressing to improve the compactness of the composite material. By the processing technology for the metal composite material, a reinforcing material (the fibers, particles or whiskers) can be mixed with the substrate metal powder in any ratio according to the designed performance requirement of the metal-based composite material.

Description

technical field [0001] The invention relates to a processing technology of a metal composite material, in particular to a processing technology of a fiber-reinforced metal matrix composite material. Background technique [0002] Metal composite materials can give full play to the respective advantages of component materials, realize the optimal allocation of material resources for each component, save precious metal materials, and achieve performance requirements that cannot be met by a single metal. It can not only replace imports and fill in domestic gaps, but also has Wide range of applications, good economic and social benefits, easy access to all aspects of support and help. For example, the development of stainless steel composite materials has always been a high-tech project actively supported and advocated by the National Development and Reform Commission and the Ministry of Science and Technology. The common metal composite materials mainly include the following ca...
