Cyclic torsion machining process capable of improving mechanical performance of metal material

Abstract

The invention discloses a cyclic torsion machining process capable of improving the mechanical performance of a metal material. The cyclic torsion machining process capable of improving the mechanical performance of the metal material comprises the following steps: step 1, smelting; step 2, pouring; step 3, rolling; step 4, heating; step 5, cooling; step 6, grain refinement; step 7, manufacturing; step 8, carburizing; and step 9, quenching. According to the cyclic torsion machining process capable of improving the mechanical performance of the metal material, in the process of preparing the metal material, rolling and heat-preservation pressurizing treatment are carried out on a blank, so that increasing for the grain refinement degree of the metal material is benefited, and then improvement for cyclic torsion performance in the mechanical performance of the metal material is benefited; and meanwhile, in the subsequent process for preparing the metal material, carburizing treatment is carried out on the metal material, so that increasing for the strength of the metal material is benefited, the phenomenon that the metal material is fractured after the metal material is cyclically twisted is avoided, and then the application range of the metal material is widened.

Description

technical field [0001] The invention relates to the technical field of metal material processing, in particular to a cycle torsion processing technology for improving the mechanical properties of metal materials. Background technique [0002] Metallic materials generally refer to pure metals or alloys in industrial applications. There are about 70 kinds of pure metals in nature, among which iron, copper, aluminum, tin, nickel, gold, silver, lead, zinc and so on are common. Alloys often refer to two or more metals or metals and non-metals combined, and have metallic properties. Among them, the existing metal materials are usually processed and prepared by conventional techniques during the preparation process, but the preparation The mechanical properties of the prepared metal material have low cyclic torsion performance. During the cyclic torsion process of the metal material, it is easy to cause the metal material to break. At the same time, the strength of the prepared me...

Alloys often refer to two or more metals or metals and non-metals combined, and have metallic properties. Among them, the existing metal materials are usually processed and prepared by conventional techniques during the preparation process, but the preparation The mechanical properties of the prepared metal material have low cyclic torsion performance. During the cyclic torsion process of the metal material, it is easy to cause the metal material to break. At the same time, the strength of the prepared metal material decreases after cyclic torsion. Reduced range of use of metal materials
