Spectroscopic analysis of magnesium-aluminum alloys by laser induced breakdown spectroscopy

Iraqi Journal of Physics, 2018
In this work, the spectra of plasma glow produced by Nd:YAG laser operated at 1.064 μm on Al-Mg alloys with same molar ratio samples in air were analyzed by comparing the atomic lines of aluminum and magnesium with that of strong standard lines.
