Abstract

The invention discloses a novel metallic material prepared from C, Si, Mn, Ni, Cr, Cu, Al, Ti, Sn, Fe and rare earth. The novel metallic material is characterized by comprising the following components by percentage: 0.2-2.4% of C, 0.3-1.3% of Si, 0.9-2.0% of Mn, 1.0-10% of Ni, 15-25% of Cr, 0.8-2.3% of Cu, 0.1-1.0% of Al, 0.1-0.8% of Ti, 0.8-1.5% of Sn, 0.6-1.7% of at least one of rare earth elements Ce and La and the balance of Fe. The mechanical property, abrasion resistance, corrosion resistance, cold resistance, heat resistance and flowability of the metallic material are improved, so that the metallic material is compact in texture and high in quality.

Description

field of invention [0001] The invention relates to a method for making a metal material, and belongs to the technical field of metal material application such as machinery. Background technique [0002] Alloy metal materials are more widely used in the current metal materials, and the general metal materials are basically composed of C, Si, Fe and other elements. These metal materials can meet general industrial needs, but in some fields that require high performance of metal materials, conventional metal materials are far from meeting the needs. my country's rare earth resources are at the forefront of the world. Due to their unique properties, infiltration of rare earth elements into steel can improve the performance of steel. Therefore, the current research on rare earth elements in the metallurgical industry has begun to be more in-depth. However, rare earth elements are generally expensive, and their addition amount and combination with those components are still...
