A multiscale continuum model of the grain-size dependence of the stress hysteresis in shape memory alloy polycrystals (2008, background): “... scales and contribute to the macroscopic hysteresis of real polycrystalline material, ranging from the interaction of interfaces with defects (impurities, dislocations and precipitates) to the interaction of interface with grain boundaries and even to the interaction between the macroscopic prop”
Phase-Transformation Fronts Evolution for Stress- and Strain-Controlled Tension Tests in TiNi Shape Memory Alloy (2006, unknown): “The interesting results of the localized phase transformation obtained for microtubes were presented in [18, 19] and completed with a proposed model in [20].”
Experimental investigation on macroscopic domain formation and evolution in polycrystalline NiTi microtubing under mechanical force (2006, background): “Experimental research on deformation instability of NiTi in microtube configuration started only in recent years (Berg, 1997; Li and Sun, 2000, Sun and Li, 2002; Li and Sun, 2002).”
