摘要

This paper presents an innovative residual stress reduction technology known as the thermomagnetic treatment (TMT) method. The efficacy of TMT is experimentally evaluated and compared, focusing on the alterations in grain boundaries and magnetic domain structures following treatment. The results demonstrate that TMT achieves a residual stress reduction of approximately 41.5%, surpassing the combined effects of the two individual methods. Characterization of the grain boundaries and magnetic domains reveals that TMT treatment narrows the grain boundaries and aligns the magnetic domains into parallel structures without inducing significant phase transitions. This analysis provides compelling evidence of TMT's effectiveness in controlling material behavior. Additionally, COMSOL simulations successfully replicate the superior stress reduction observed with TMT and elucidate the underlying mechanisms contributing to its outstanding performance.
