| Abstract: | This paper discusses the technology of refining domain wall space decreasing iron loss and improving nature of silicon steel sheet by pulse laser irradiation. Through the mathematical model established, the photo thermoplastoelastic stress induced in sheet by irradiation process is analyzed and critical stress of effect of optimum irradiation calculated. Therefrom the optimum technological parameters would be determined by laser irradiation. |
