Title:
ULTRASONIC ROLLING SURFACE STRENGTHENING PROCESS FOR MEDIUM-ENTROPY ALLOY PLATE
Document Type and Number:
WIPO Patent Application WO/2022/041694
Kind Code:
A1
Abstract:
The present invention relates to an ultrasonic rolling surface strengthening process for a medium-entropy alloy plate, comprising the following steps: S1: preparing metal raw materials into a medium-entropy alloy ingot according to components of a medium-entropy alloy; S2: cutting, by means of a lathe, the alloy ingot into an alloy plate having a smooth surface; S3: separately mounting the alloy plate and an ultrasonic rolling strengthening tool on a numerically controlled machine tool, and setting a spring compression amount of the ultrasonic rolling strengthening tool, a machine tool feeding path, and a machine tool feeding speed; S4: providing and starting an ultrasonic generator, and regulating to a preset frequency and a preset amplitude parameter; S5: turning on the numerically controlled machine tool, performing covering rolling processing on the surface of the alloy plate, and uninterruptedly cooling and lubricating the surface of the alloy plate in the processing process; and S6: repeatedly executing step S5 until a preset requirement is met, thus obtaining a medium-entropy alloy plate of a nano gradient structure. The plate prepared by using the ultrasonic rolling surface strengthening process of the present invention has high strength and a smooth surface.
