摘要：
In matrix, the precipitates play a key role in adjusting the properties of martensitic transformation for improving the reversible strain of the Fe-Ni-Co-based shape memory alloys. Kinetics of the precipitation transformation during aging at 873 K in Fe-31.88Ni-10.63Co-3.83Ti alloy was characterized by in situ Electrical Resistivity and illustrated by the JMA equation. The changing of the MS temperatures and the hysteresis of martensitic transformation corresponding to different aging time was also characterized by the magnetization method. The mechanism about the effect of precipitates on martensitic transformation is discussed. (C) 2015 The Authors. Published by Elsevier Ltd.
