摘要：
Transformation behaviors and shape memory characteristics of Ti-N-35-Cu-15 alloy ribbons prepared by melt spinning were investigated by means of DSC, XRD, OM and TEM. An increase of the superheat of the melt leads to a reduced ribbon thickness and a refinement of grains. It was found that the microstructural refinement achieved by controlling the melt-spinning temperature decreased M-s significantly. (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd.
