Rapid Determination of the Temperature Field and of the Geometry of the Hardened Zone in the Heat Treatment by a Powerful Laser Beam |
| |
| Abstract: | The present work proposes a method which can be used for a rapid calculation of the temperature field caused by a powerful laser during a superficial heat treatment. Using this result, we propose a method which can be used in order to assess the geometry of the hardened zone. These methods do not only allow us to calculate for any kind of beam energy repartition but also with a speed 100 times quicker than with traditional numerical methods. |
