Title:
METHOD FOR PREPARING TUNGSTEN PARTICLE-REINFORCED METAL-BASED COMPOSITE MATERIAL ON BASIS OF 3D PRINTING TECHNOLOGY
Document Type and Number:
WIPO Patent Application WO/2020/056535
Kind Code:
A1
Abstract:
The present invention relates to the technical fields of particle-reinforced metal-based composite materials and 3D printing, and relates to a method for preparing a tungsten particle-reinforced metal-based composite material on the basis of three-dimensional (3D) printing technology. The present invention uses 3D printing technology to prepare a tungsten particle-reinforced metal-based composite material, wherein the proportions of a tungsten-reinforced phase and a matrix phase in the composite material may be adjusted and controlled within a relatively large range. The present invention may have a strong design, a simple process, a short preparation cycle and low costs. Moreover, in the tungsten particle-reinforced metal-based composite material prepared by the described method of the present invention, tungsten-reinforced phase particles are uniformly distributed on the matrix phase, the tungsten-reinforced phase particles are fine, and the grains are not significantly grown and have excellent mechanical properties.
