The equiatomic face-centred cubic (FCC) CoNiCrFeMn alloy, known as the Cantor alloy, is renowned for its high ductility under extreme conditions, such as cryogenic temperatures. Despite this, it suffers from low hardness and yield strength (YS) and i

A computational framework is developed to understand the transient behavior of isothermal and non-isothermal transformation between liquid and solid phases in a binary alloy using a phase-field method. The non-isothermal condition was achieved by app

During welding, work-pieces are melted to form a weld pool and are joined upon solidification. The quality of the welded product is largely determined by the solidified microstructure and solute distribution. In recent years phase-field (PF) models h
