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

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 …

The structural evolution in NiTi shape memory alloys subjected to pseudoelastic cycling is
examined in the present study. Single crystals with [100] and [111] orientations were …

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 …

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 …

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 …

Owing to its importance in understanding the mechanical and thermomechanical behaviours
of shape memory alloys (SMAS). the deformation mechanism of martensitic twins has been …

NiTi shape memory wire was deformed in martensite state at low temperature− 125° C up to
750 MPa stress and subsequently heated far above the A f temperature while the stress 750 …

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 …

Room temperature monotonic and cyclic stress–strain curves for single crystal and
polycrystalline NiTi shape memory alloys containing Ti3Ni4 precipitates are presented. The …
