Abstract Martensitic Ni 50 Ti 50 wires and sheets with different textures were tensile tested in
the temperature range between− 100° C and 60° C. The effect of texture and temperature on …

The stress–strain curves of polycrystalline martensitic NiTi shape memory alloys are often
different for loading under tension and compression. Under tension, a flat stress-plateau …

Thermal cycling experiments were conducted on a NiTi shape-memory alloy at different
constant applied stresses below the yield strength of the martensite. The mechanical strain …

Superelastic NiTi wires were deformed in tension up to gradually increasing total strains at
various temperatures, recoverable strains were evaluated and lattice defects left in the …

The microstructural evolution of a near equiatomic NiTi shape memory alloy has been
studied by in situ synchrotron diffraction, whilst being thermally cycled under an applied …

For a cold-rolled NiTi sheet, the tensile stress–strain curves show a flat stress-plateau during
tension along the rolling direction, while under tension along the transverse direction the …

It was observed that the reverse transformation of stress-induced martensite occurred at a
temperature some 20 K higher than that of thermal martensite. The increase in temperature …

Much progress has been made over the past few decades in resolving the mechanism for
the transformation from ordered body-centered-cubic (B2) austenite to monoclinic martensite …

NiTi shape memory alloys are used in practice in their polycrystalline form and usually
consist of strong textures. The present research aims to understand the anisotropy in the …

Experimental results have shown that, during mechanical cycling under tension–
compression load within±4% strains, the NiTi shape memory alloy is cyclic strain-hardened …
