Glass forming ranges of Al–rare earth metal alloys: thermodynamic and kinetic analysis

摘要

Using CALPHAD databases, chemical short-range ordering is analyzed and related to metastability of undercooled melts of Al–rare earth metals (including Ce, Gd, Nd and Y). A quasi-kinetic analysis of the primary crystallizations predicts the best glass forming ranges for the quenched alloys, in agreement with those experimentally determined.
