FE Based Transforming Single Crystals
ABSTRACT
We report on the stress-strain response of Co-Ni-Al with a two-phase microstructure which displayed an unusual decrease
in critical stress (84%) with strain or thermal cycling accompanied with an improved recoverability of pseudoelastic and shape
memory strains. The repeated deformation also produced a decrease in stress hysteresis and a reduction in residual strain
making this material rather attractive for ferromagnetic shape memory applications.
