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 …

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 …

Functional stress-strain–temperature responses of superelastic NiTi wire in purposely
designed thermomechanical tests in tension were evaluated and lattice defects created by …

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 …

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 …

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

Temperature dependent deformation of the B2 austenite phase of a polycrystalline Ni 49.9 Ti
50.1 (at.%) shape memory alloy was studied through combined macroscopic and …

The objective of this study is to examine the effect of heat treatment on polycrystalline Ti–
50.9 at.% Ni in hot-rolled and cold-drawn states. In particular, we examine microstructure …

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 …
