The transformation temperatures of NiTi-based alloys strongly depend on the number of (valence) electrons. It has been argued that the Ms of Ni0.50−xTi0.50−xMn2x is independent of x, because e/a = 7.00, unchanged relative to Ni0.50Ti0.50, for any x. In this work, a model is presented, in which it is argued that not only changes in the number of electrons, but also band-structure changes should be considered. The calculations, made with this model, are confirmed by experimental results.
