Problems solved by technology

[0004] It can be seen that the current patents on high manganese steel mainly focus on the alloying and rare earth modification of high manganese steel using traditional processes. The performance improvement of high manganese steel is very limited, and it cannot fully adapt to medium and low impact stress conditions.

Abstract

The invention discloses a preparation process of a high manganese steel based composite material, which mainly includes the following steps: weaving a molybdenum wire mesh by using molybdenum wires, and manufacturing a reticular three-dimensional framework structure by cutting, multilayer rolling or superposing; manufacturing a casting mold according to casting process requirements, and pre-placing the molybdenum wire three-dimensional reticular framework into a cavity of the casting mold; smelting high manganese steel to obtain liquid high manganese steel which is poured into the casting mold, and obtaining molybdenum wire-high manganese steel binary material preform after cooling and clearing; and placing the molybdenum wire-high manganese steel binary material preform into a heat treatment furnace, heating to a temperature at which carbide is formed, preserving heat, and obtaining molybdenum carbide particle reinforced high manganese steel based composite material. The composite material prepared by using the method fully plays the high abrasion resistance of molybdenum carbide hard phase and the good toughness of the high manganese steel, the regulation and control are convenient, and the process is reliable, thus solving the problems of incomplete reaction of the composite material, the uneven distribution of reinforced phase particles, the pollution weakening of reinforced phase interfaces and the like; and the composite material can be widely applied in the fields of wear resistance such as mines, electric power, metallurgy, coal, building materials and the like.

Description

technical field [0001] The invention belongs to the technical field of metal-based composite materials, and in particular relates to a preparation process of high-manganese steel-based composite materials. Background technique [0002] High manganese steel has high strength, plasticity, low temperature toughness, work hardening, and impact resistance safety. As a wear-resistant material, in terms of resistance to abrasive wear or chisel wear under strong impact and high pressure, its wear resistance under high impact stress conditions is unmatched by other materials. Wear-resistant products such as liners, hammer heads, screen bars, and jaw plates made of high manganese steel have been widely used in metallurgy, mining, building materials, railways, electric power, coal and other mechanical equipment for a long time. However, it has been found in practice that the wear resistance of high manganese steel is conditional, and the high wear resistance of high manganese steel ca...
