Shape recovery mechanism observed in single crystals of Cu-Al-Ni shape memory alloy

摘要

Micromechanism of the shape recovery process is optically observed in single crystals of the Cu-Al-Ni shape memory alloy. Formation of X and λ-interfaces (interfacial microstructures with two intersecting habit planes) is documented, both in a thermal gradient and during a homogeneous heating. The observed growth mechanisms (i.e. mechanisms of nucleation and growth of the twinned structures) are described and analysed. Weakly non-classical boundaries between austenite and two crossing twinning systems are also documented.View full textDownload full textKeywordsshape memory alloys, shape recovery process, martensitic microstructure, non-classical boundariesRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/01411590801891616
