Rapid Solidification of Alloy Substrates by Lasers and Electron Beams: Heat Flow Modelling and Solidification Morphology
Abstract
dc:descriptionA combined theoretical and experimental study is described for the rapid melting and solidification of pure aluminum and aluminum copper alloy substrates subjected to a high intensity heat flux. The problems addressed are for stationary or moving heat fluxes absorbed through a circular region on the bounding surface of the semi-infinite substrates. The most important contribution of this study is the development of a new heat flow model and solidification of an alloy substrate over a range of temperatures, and the verification of same with steady-state experiments on an Al-4.5 wt.% Cu alloy substrate.
