Ductile shape memory (SM) alloys of the Cu-AI-Mn system have been developed by
controlling the degree of order in the β phase. Additions of Mn to the binary Cu-Al alloy …

The effects of various structure factors on the properties (superelasticity mainly) of Cu-based
shape memory alloys (SMAs) were systematically evaluated in this review article through …

In shape memory alloys, the reversible phase transformations between austenite and
martensite give rise to superelasticity and shape memory properties. Here we systematically …

Abstract Polycrystalline Cu–Al–Mn shape memory alloys (SMAs) with a low degree of order
of the β (L21) phase show excellent ductility and exhibit shape memory (SM) properties such …

The operation temperature window is one of the key parameters for the refrigeration
application of elastocaloric materials. In the present work, we investigated the relationship …

In this study, it is proposed that coarsening austenitic grains is a key criterion for achieving
giant recovery strains in polycrystalline Fe-Mn-Si based shape memory alloys. In order to …

Cu-Al-Mn shape memory alloys with enhanced ductility have been developed by decreasing
the degree of order in the β parent phase. Cu-Al-Mn alloys with Al contents lower than 18 …

The effect of grain size on thermal hysteresis is studied in ribbons and thin strips obtained by
rapid solidification techniques. Results show a strong increase of the hysteresis width when …

The Cu-Mn-Al alloys exhibit, in a certain range of composition, an A2 (BCC) phase which is
stable at high temperatures (around 1,050 K). Two ordering reactions take place on lowering …

The morphology of the martensitic transformation during a superelastic cycle is studied by in
situ scanning electron microscopy deformation experiments in microwires of Cu–Zn–Al. The …
