研究目的
To calculate the temperature distribution on the surface and bulk of a steel plate under the laser hardening process.
研究成果
The temperature distribution along the x-axis and z-axis are contrary developed by time where the peak shift and slope of temperature distribution as well symmetry of the distribution is in contrast to each-other. The model can be extended to find the interfere of the impurities and other alloys present in the medium as well.
研究不足
The model assumes the laser produces relativistic flow of electrons and does not account for the interference of impurities and other alloys present in the medium.
1：Experimental Design and Method Selection:
The model starts from the basic heat equation, developed to a volumetric form connected to various solid phases.
2：Sample Selection and Data Sources:
Steel plate (H13) with 3D shape under laser hardening process.
3：List of Experimental Equipment and Materials:
Laser hardening process parameters including velocity of the laser spot and irradiation time.
4：Experimental Procedures and Operational Workflow:
The model assumes the laser produces relativistic flow of electrons by heating the surface, uniformly moving the laser in X-axis on the surface.
5：Data Analysis Methods:
The temperature distribution is calculated at different times of the laser hardening process and compared to available experimental data.
