摘要：

Despite having a negative heat of mixing, a metastable liquid/amorphous miscibility gap (MLMG) was found below the liquidus of the alloy system, Pd-Ni-P. Earlier, a direct determination of the complete MLMG was not possible because it lies in the undercooling regime. It is known that the morphology of an alloy system that has undergone a spinodal mechanism is interconnected. In this work, a morphological transition, from eutectic to interconnectedness, was used to determine the complete MLMG of the alloy system, Pd-Ni-P. (C) 2015 Elsevier B.V. All rights reserved.
