Resistometric and X-ray investigation of (Ni2Cu)1−x Sn x alloys

Abstract

Resistometric measurements have revealed the approximate position of the solvus line in the isopleth phase diagram of (Ni2Cu)1−xSnx alloys for Sn content between 0 and 14 at.% and temperatures between 600 and 900°C. The data were analyzed on the ground of a model which takes into account their dynamic character. Within the two-phase region they indicate the existence of two different phase-states of the system. Control X-ray measurements have shown that in the high temperature region above approx. 700°C the second phase is of theDO3 structure. Our results are in variance with published data.
