Description

Technical Field

[0001] This utility model relates to the field of high-entropy alloy processing technology, and in particular to a processing device for removing residual stress from high-entropy alloys. Background Technology

[0002] Alloys are metallic materials with metallic properties formed by alloying two or more metallic elements or by adding other non-metallic elements to a metal base through alloying processes (smelting, mechanical alloying, sintering, vapor deposition, etc.). High-entropy alloy pipe fittings are widely used in modern industrial production. During the processing of hard high-entropy alloy pipe fittings, grinding equipment is needed to remove burrs on the inner wall. Currently, existing alloy processing equipment results in high internal stress levels, poor dimensional stability, and easy deformation during processing. Common stress relief methods include heat treatment and natural placement. Heat treatment is expensive and causes deformation and cracks, altering the appearance. Natural placement is time-consuming and space-consuming. Therefore, it is necessary to improve these methods and design a processing device for removing residual stress from high-entropy alloys.
