摘要

The CALPHAD approach is applied to the study of stability and aging of several Ni-Cr-Mo alloys similar to those considered for use in waste disposal containers for the Yucca Mountain Project (YMP). The stability of occurring phases in the as-fabricated materials must be investigated since their precipitation with time at temperature can reduce their corrosion resistance and mechanical properties. We first show that excellent agreement exists between assessed and calculated phase diagrams for the three major binary alloys, Ni-Cr, Ni-Mo, and Cr-Mo, and for the ternary Ni-Cr-Mo alloy. Then we present a comparative study of phase fractions versus temperature for the nominal composition of several multi-component Ni-Cr-Mo alloys. Finally we discuss the aging properties of the Ni_2Cr-ordered phase in Ni-Cr and in Ni-Cr-Mo alloys, and of the complex P phase in Alloy 22.
