Resumen
The aim of this work is to develop a mathematical model based on the finite difference method in order to simulate the remelting process. Good agreement between numerical and experimental results was obtained in the delimitation of the remelted zone. The work also concerns the analysis of the microstructural and hardness variations throughout samples of an aluminum-copper alloys (Al-15 wt pet Cu) submitted to a laser surface remelting treatment. The specimens were examined by optical and scanning electron microscopy. Microhardness measurements were carried out on the transverse section for the resolidified and unmolten regions. 7
