Numerical Simulation Of Heat Affected Zone Microstructure During Laser Surface Melting

Microstructural changes during laser welding and laser surface treatment has been regarded by many researchers. Most researches have focused on studying the effect of various process parameters on the size and microstructure of the heat affected zone. But some studies show that the initial microstructure of the base metal can also affect the heat affected zone dimensions and final microstructur...

Molecular dynamics studies of ultrafast laser-induced nonthermal melting

Molecular Dynamics (MD) is employed to investigate nonthermal melting triggered by coherent phonon excitation in bismuth telluride, which has Peierls distortion in the lattice structure. Results showed that the structural distortion caused by coherent phonons appears as early as 80 fs, while it takes several picoseconds for the whole phononexcited area to evolve into a liquid state. It was also...

Microstructure and Hardness of Surface Melting Hardened Zone of Mold Steel, SM45C using Yb:YAG Disk Laser

This study applied laser surface melting process using CW(Continuous wave) Yb:YAG laser and cold-work die steel SM45C and investigated microstructure and hardness. Laser beam speed, power and beam interval are fixed at 70 mm/sec, 2.8 kW and 800 μm respectively. Depth of Hardening layer(Melting zone) was a minimum of 0.8 mm and a maximum of 1.0 mm that exceeds the limit of minimum depth 0.5 mm a...

Quantum Hooke's Law to Classify Pulse Laser Induced Ultrafast Melting

Ultrafast crystal-to-liquid phase transition induced by femtosecond pulse laser excitation is an interesting material's behavior manifesting the complexity of light-matter interaction. There exist two types of such phase transitions: one occurs at a time scale shorter than a picosecond via a nonthermal process mediated by electron-hole plasma formation; the other at a longer time scale via a th...
