Dataset on the microstructure Ni 50Mn 38Sb 9Si 3 alloy and compositions of Ni 50Mn 38Sb 12? x Si x ( x=2.5, 3) ferromagnetic shape memory alloys

摘要

The data presented in this article is the supplementary data of?Zhang et al. (2018) . The Ni 50 Mn 38 Sb 9 Si 3 alloy is annealed at 1223?K for 24?h and then quenched into ice water; while the Ni 50 Mn 38 Sb 9.5 Si 2.5 alloy is annealed at 1173?K for 24?h and then quenched into ice water. The microstructure of the Ni 50 Mn 38 Sb 9 Si 3 alloy indicates that a higher heat treatment temperature cannot prevent the formation of secondary phases. Furthermore, the composition of α phase is similar to the nominal composition of the alloy. On the other hand, the nominal concentration of Si atoms and heat-treatment temperature do not affect the compositions of the β and γ phases. For example, the compositions of the β and γ phases in the Ni 50 Mn 38 Sb 9 Si 3 alloy are similar when annealed at 1223?K for 24?h and 1173?K for 24?h.
