The effect of aging (at 773 K for 1 h) on the cyclic stability superelasticity was studied in preliminarily quenched (after annealing at 1448 Ni44Fe19Ga27Co10 [001]-oriented single crystals. It shown that NiFeGaCo crystals (both and aged) exhibited highly stable during more than 105 loading/unloading cycles compression without destruction. degradation curves divided into stages, each stage care...

In this work, we report an anomalous phenomenon on superelastic cycling of NiTi shape memory alloys when deforming at the temperature close to border window. New unexpected effects are found—(i) critical stress for inducing martensite transformation during second loading cycle is higher than that first cycle; (ii) plateau decreases original level strain overcomes limit (iii) transition from goo...

impact responses of rectangular composite plates with embedded shape memory alloy (sma) wires are investigated in the present research. the plate is assumed to be placed in a thermal environment; so that in contrast to the available researches in the field, the shape memory and ferroelasticity effects have to be considered also in addition to the superelasticity. the governing equations are der...

NiTi based shape memory alloys are one of the most intensely studied from its class. Therefore, diverse commercial applications have been developed due to certain properties such as: effect, superelasticity and corrosion resistance. Currently, main automotive manufacturing aerospace actuators, biomedical devices or pipe couplings. In recent years, alloyed with a third element in order improve a...
