Laser Micro-Processing Of Amorphous And Partially Crystalline cu45Zr48Al7 Alloy

This paper presents a microstructural study of laser micro-processed high-purity Cu45Zr48Al7 alloys prepared by arc melting and Cu-mould casting. Microprocessing of the Cu45Zr48Al7 alloy was performed using a Rofin DC-015 diffusion-cooled CO2 slab laser system with 10.6-µm wavelength. The laser was d...
