Abstract

The invention discloses a microstructure and mechanical property testing method for ultrasonic shot peening induced nano-alloying. The testing method comprises the specific steps that first, a test technician writes test steps, grasps test matters needing attention and prepares test materials and equipment; second, Q235 steel plate samples are prepared and tested in groups, wherein the tests include that a, the Q235 steel plate sample 1 is maintained; b, the Q235 steel plate sample 2 is subject to ultrasonic shot peening under 30kHz power for 5min; c, Cr powder is added, and then the Q235 steel plate sample 3 is subject to ultrasonic shot peening under 30kHz power for 20min; d, Cr powder is added, and then the Q235 steel plate sample 4 is subject to ultrasonic shot peening under 30kHz power for 10min; and e, Cr powder is added, and then the Q235 steel plate sample 5 is subject to ultrasonic shot peening under 20kHz power for 10min; and third, a scanning electron microscope is utilizedto perform ray scanning on sample surface regions in the five tests performed in the second step respectively. The microstructure and mechanical property testing method for ultrasonic shot peening induced nano-alloying is simple, practical and convenient to operate, the obtained conclusion is representative, and the method is suitable for wide application and popularization.

Description

technical field [0001] The invention belongs to the technical field of testing and testing, and in particular relates to a microstructure and mechanical property testing method of nano-alloying induced by ultrasonic shot peening. Background technique [0002] Shot peening is a material surface treatment method that is frequently used in industrial production. Shot peening aims to strengthen and improve certain properties of the material surface, so it is also called enhanced shot peening. Some mechanical components are strengthened after shot blasting, which significantly improves the strength and stress resistance of the parts. During the production test, it is necessary to test the microstructure and mechanical properties of the workpiece after ultrasonic shot blasting, which cannot be accurately measured. The performance of the workpiece under different shot blasting conditions, and the data obtained from the test test are not representative, the detection method is more ...
