Abstract
The orientation dependence of the martensitic transformation characteristics and superelasticity were investigated in the Fe 43.5 Mn 34 Al 15 Ni 7.5 single crystalline shape memory alloy along the [100], [111] and [123] orientations under compression. Solution heat treated samples exhibited a strong orientation dependence of the slopes for the stress vs. temperature phase diagrams (i.e. Clausius-Clapeyron slopes), while peak-aged samples demonstrated reduced orientation dependence. Maximum superelastic strains determined in the experiments along various single crystal orientations match well with the theoretical predictions.
