摘要: Aluminium 7178 samples were prepared and irradiated with Nd:YAG laser. The surfaces of exposed investigated using optical microscopy, which revealed that the surface morphology is changed drastically as a function laser shots. It from micrographs heat effected area increases increase in number pulses. Furthermore morphological mechanical properties studied XRD Vickers hardness testing. study shows an increasing trend Grain size And shots first then it decreases gradually. was observed grain has no pronouncing effect on hardness. Hardness profile decreasing linear distance boundary affected area.
