Abstract Scope |
In the frame of solid/liquid transitions in metals, melting has been much less studied than solidification owing to the preeminence of traditional metallurgical techniques such as casting. However, melting receives a recent increasing attention linked to the developments of additive manufacturing processes, for which the properties of the final product depends crucially on a succession of melting and solidification stages. Here, we present our work, illustrated by phase-field simulations, on several melting scenarios such as the melting of a peritectic phase, the remelting/resolidification mechanisms taking place when, for example at the bottom of a melt pool, the mushy zone is held in a static thermal gradient, and the so-called grain boundary pre-melting for which an atomically thin liquid layer grows along the latter below the melting temperature. |
