摘要	Temperature memory effect can be induced by incomplete transformation upon either heating or cooling in TiNi shape memory alloys (SMAs). An incomplete cycle on heating (ICH) of shape memory alloy arrested at a temperature between A(s) and A(f) induce a kinetic stop slight higher than the arrested temperature in the next complete transformation cycle. An incomplete cycle on cooling of a shape memory alloy arrested at a temperature between M-s and M-f induce an increase of the transformation heat of the reverse transformation with a decrease in the arrested temperature in the following heating for a sample without R-phase transformation. And for a sample with R-phase transformation, when the stop temperature arrested in the temperature range between R-f and M-s, the heat flow detected upon following heating only shows one endothermic peak. With decreasing arrested temperature T-s to the temperature range between M-s and M-f, two endothermic peaks can be found upon the following heating. With decreasing arrested temperature T-s the transformation heat of the first peak decreases and that of the second peak increases. (C) 2004 Elsevier B.V. All rights reserved.
