|Title:||Numerical And Experimental Analysis Of Laser Surface Remelting Of Al- 15cu Alloy Samples|
|Abstract:||The aim of this work was to develop a heat transfer mathematical model based on the finite difference method in order to simulate temperature fields in the laser surface remelting process. Convective heat transfer in the remelted pool was taken into account by using the effective thermal conductivity approach. Theoretical predictions furnished by previous models from the literature and results of experiments of laser surface remelting of Al-15Cu samples, carried out in the present investigation, were used for validation of numerical simulations performed with the proposed model. The work also encompassed the analysis of microstructural parameters by scanning electron microscopy and microhardness variations throughout the resulting treated and unmolten zones. © 2005 Institute of Materials, Minerals and Mining.|
