Microstructure evolution and phase analysis of Sm60Ni40 alloy
Source abstract
Abstract
The paper investigates the microstructure evolution and phase analysis of the Sm 60Ni 40 alloy. The arc melted sample retained the high temperature stable (>873 K) Sm 7Ni 3 and Sm 3Ni 2 phases along with the congruently melting SmNi phase. Annealing the as-cast sample at 903 K for 100 h stabilized the high temperature stable (873 K − 903 K) Sm 3Ni 2 phase. Rietveld refinement was performed to resolve the crystal structure of Sm 3Ni 2 phase and it was observed that Sm 3Ni 2 phase stabilizes in monoclinic crystal structure (space group: C2/ m) with a lattice parameter of a = 13.49 Å, b = 3.75 Å, c = 9.68 Å and β = 106.6°. The Curie temperature of the Sm 3Ni 2 phase was determined to be ∼ 110 K. The high squareness ratio of 82 % along with high coercivity of 3 T indicates that the Sm 3Ni 2 phase possess spontaneous uniaxial magnetic anisotropy.
