In cu-based shape memory alloys, some alloys have a much higher transformation temperatures while others have a very low transformation temperatures down to negative, what are reasons behind this?!!!
Pavel N. Yakushev
The concentration of the constituents of the alloy has the greatest influence.
The effect is in a very narrow concentration range.
In addition, the magnitude of the deformation (through the load) during the "charging" of the sample also plays a role.

Generally, the following are the significant factors affecting shape memory alloys' transformation temperatures.
1. Alloy composition (e/a ratio, valance electron concentration, atomic size)
2. Thermomechanical treatments (Annealing, hot/cold deformation, aging)
3. Grain size
4. Defect density.
