Strain Concentration Effect in Cu–Al–Ni Single Crystals under a Longitudinal Bending Force

Аннотация

The behavior of a superelastic Cu−14.2% Al−4%Ni single crystal in the case of high reversible strains under a longitudinal bending force was investigated. The effect of strain confinement along the crystal length was revealed and studied. The highest reversible strains (up to 10%) were shown to be confined within the central part of the bent crystal.
