“…The shape memory alloys are widely noticed because of their good hot/cold workability.  base Co-Ni-Al alloys have the B2 → L1 0 phase transformation, the Curie and the martensitic transition temperatures of the  phase increase and decrease with increasing the Co content, respectively [7,8]. Chen and Han [10] have added Co into NiAl and show that the compressive strength and compressive ductility of the stoichiometric NiAl have been greatly improved by adding proper amount of Co.…”
