Abstract
Aging effects on the transformation temperatures and the deformation behavior of Ti-Ni alloys have been studied by electrical resistivity measurement, tensile test and transmission electron microscopy. Main interest was in the influence of alloy composition and aging treatment on the pseudo-elasticity and the shape memory effect. It was found that Ms temperature and mechanical behavior of nickel-rich off-stoichiometric (>50.7at%Ni) Ti-Ni alloys were sensitive to heat-treatment, while those of a near-stoichiometric (50.4at%Ni) alloy were not. Precipitates were observed in the off-stoichiometric alloys after agingKeywords
