Abstract
AbstractIn V45Ti30Ni25 (at. pct), superelastic TiNi and a stable V-rich bcc phase (β) coexist in multiple-phase mixtures with each acting as matrix and precipitate. Through nano-indentation measurements and in situ synchrotron and SEM tensile tests coupled with digital image correlation analysis, the phase mixtures are revealed to exhibit similar strain-partitioning behaviors but different dependencies of reverse transformation on strain. These insights on multi-phase plasticity provide hints for improved damage resistance in the presence of a superelastic phase.
