The effect of grain size on the martensitic transformation in Ni42Ti shape memory alloy has been studied. The kinetics of grain growth has been evaluated and the influence of different grain sizes on the transformation temperatures and the thermodynamic magnitudes has been reported. Image analysis a

High-precision data on phase transformation temperatures in NiTi, including numerical expressions for the effect of Ni on M S , M F , A S , A F and T 0 , are obtained, and the reasons for the large experimental scatter observed in previous studies are discussed. Clear experimental evidence is provid
Usually aged Ni-rich NiTi alloys undergo martensitic transformations on cooling from high temperatures in two steps: B2 to R and then R to B19Π (normal behaviour). But under certain ageing conditions, the transformation can also occur in three or more steps (unusual multiple step behaviour). In the
