Phase Stability at Martensitic Transformation in Zr-Based Shape Memory Intermetallics

Abstract:

This article is dedicated to the estimation of the relative stability for B2, B19`, B33 and Cm phase in ZrCu-ZrNi-ZrCo intermetallic compound row through the ab-initio electronic structure calculations and subsequent crystal structure Rietveld refinement. The information about electronic and crystal structure of phases in Zr-based intermetallics will allow selecting for this high temperature shape memory alloy such alloying elements that will significantly improve shape memory behavior through definite structural changes.
