Deformation behavior and microstructure evolution of NiTiCu shape memory alloy (SMA), which possesses martensite phase at room temperature, were investigated based on a uniaxial compression test at the temperatures of 700~1000 ◦C and at the strain rates of 0.0005~0.5 s−1. The constitutive equation of NiTiCu SMA was established in order to describe the flow characteristic of NiTiCu SMA, which is...

The effect of large-strain cold-to-warm deformation on the microstructures and mechanical properties various steels alloys is critically reviewed. review mainly focused microstructure evolution, whereas textures are cursorily considered without detailed examination. in a wide strain range, from early straining to severe deformations. Such an approach offers clearer view how mechanisms affect st...

In this paper, the deformation and phase transformation of disordered α in (α + γ) two-phase region as-forged Ti-44Al-8Nb-(W, B, Y) alloy were investigated by hot-compression hot-packed rolling. The detailed microstructural evolution demonstrated that deformed microstructure was significantly affected conditions, differences mainly due to use a lower temperature strain rate. Finer grains formed...
