Theoretical calculation of the laser transformation hardened layer |
| |
| Abstract: | The width and depth of laser transformation hardened layer was evaluated by establishing temperature field mathematical model and applying numerical calculation. Experimental results showed that the relative errors of width and depth of hardened layer between theoretical calculation and experimental result were 3.33% and 7%, which proved that this model had some practical value for real processing and guiding significance for theory. |
