Abstract: As an efficient and environmentally friendly physical processing method, ultrasonic technology has broad application prospects in the field of metallurgy and material preparation. This paper analyzes the problems existing in the current teaching of the course application of ultrasonic technology in metallurgy and material preparation, such as the disconnection between theory and practice, outdated teaching content, and lack of cutting-edge scientific research results. In order to solve these problems, the article proposes a series of teaching reform measures, including strengthening the combination of theory and practice, introducing cutting-edge scientific research results, and promoting interdisciplinary integration, it is aimed to improve students'practical ability and innovative thinking, and cultivate their scientific research ability and innovative spirit.
