Following aging under stress, Ni-rich TiNi shape memory alloys are subject to a two-way shape memory effect known as the “All Round Memory Effect” (ARME). The latter causes a sample to return to its high temperature shape during heating after being spontaneously deformed on cooling during martensiti...
