Abstract: This study theoretically investigates the effects of the entrainment accompanying mass, momentum, and energy transport on pore size during high power density laser and electron beam welding processes. The physics of ...

Abstract: This study shows that there exist a pair of universal and unique phase diagrams to describe general development of the pore shape in solid, resulting from a bubble captured by a solidification front. Like thermodynamics, ...

Abstract: The pore sizes affected by different drilling parameters during high power density laser and electron beam welding processes are theoretically determined in this study. The drilling parameters include incident energy ...

Abstract: The effects of entrainment accompanying mass, momentum, and energy transport from the keyhole wall on keyhole collapse during highpowerdensity laser or electron beam drilling are theoretically and systematically investigated ...
