Enhancing mechanical characteristics by adding nanoparticles and employing lasers in heat treatment

Abstract

With the development of laser technology in various fields of engineering and manufacturing in terms of many uses in these areas and in the field of improving the mechanical properties of different metals for their ability to withstand different thermal and mechanical stresses and stresses. Wherein this research paper the addition of nanomaterials and laser heat shedding on them and knowing their ability to improve. The design process of the simple model that complies with the requirements of the simulation process was in the solid works program. The investigated dimensions were (100×100×10) mm3 in height, split up in the form of two portions. The partition itself is the path of the laser used. It is necessary to check the reliability of the mesh to form an appropriate mesh that can give accurate results. The nanoparticles where Al2O3 and TIC were used in different proportions with the base material. Which is steel, where these ratios were (0.3, 0.6, 1) wt %, where the results proved the process of adding nanomaterials has positive effects in terms of the materials' tolerance to heat, mechanical stress, and the surrounding conditions. Seen through the results with the increase in the concentration values of adding nanoparticles, get a significant effect on the results and the values of thermal and mechanical properties. The TIG (Tungsten inert gas) nanomaterial led to an increase in temperatures in the solid by 1 wt % compared to the rest of the concentrations and nanomaterials. The addition of nanomaterials in heat treatments has a positive effect on the amount of deformation, as the lowest value of deformation was obtained in nanomaterials at tic1 wt % compared to the rest of the concentrations. As for the stresses, the largest stress obtained is 10.502 Gpa
