Abstract: Abstract The realisation of the recoverable strain variation by ultrasonic vibrations was studied in shape memory bimetallic strips produced by explosion welding. Two bimetal “Ti49.4Ni50.6–AISI 304” and “Ti50Ni50–Ti49.3Ni50.7” strips were deformed to 5% and subjected… read more here.

Abstract: Abstract This paper investigates the degradation of the recoverable strain during full transformation cycling in shape memory alloys. Results show that such degradation occurs due to: (i) untransformed austenite during full transformation, (ii) residual martensite… read more here.

Abstract: Large recoverable strain of more than several percent arising from superelasticity in shape memory alloys is important for actuators, sensors, and solid-state refrigeration. Here, we report a Ni50.0Mn31.4Sn9.6Fe9.0 magnetic microwire showing a giant tensile recoverable… read more here.
