On the effect of titanium on quenching sensitivity and pseudoelastic response in Fe-Mn-Al-Ni-base shape memory alloy

abstract

• 2016 Elsevier Ltd In the present study, the effect of Ti addition on the microstructure evolution and pseudoelastic properties of a Fe-Mn-Al-Ni shape memory alloy were investigated. By replacing 1.5 at.% Al by Ti in Fe-Mn-Al-Ni, it was possible to strongly hamper the formation of the ductile, non-transforming -phase, which is detrimental to the pseudoelastic performance. Single crystalline samples were fabricated via abnormal grain growth. Following aging treatment at 250 C compression testing at various testing temperatures was conducted up to 10.5% strain using a near 102 oriented single crystal. A low Clausius-Clapeyron slope and good pseudoelastic properties were found.
