Ni-Mn-Al Heusler Alloy Samples Preparation by Mechanical Alloying Method and Study of their Investigated Properties

Objective: In this work, ternary Ni-Mn-Al Heusler alloy powder samples were fabricated using mechanical alloying technique to study its formation mechanism and the effects of on investigated properties. Methods: The prepared high energy planetary ball mill under argon conditions. milling time 0 h (hour/hours), 5 h, 10 15 selected see progress formation. microstructural, compositional, thermal magnetic studies milled conducted. Findings: Compositional reveals stoichiometric composition (X2YZ) with no contamination. optimum required for by resulted through proper selection parameters. average crystallite size obtained that nanocrystalline structure was achieved during operation. successive heating particles in differential scanning calorimetry showed crystallization Novelty/Applications: indicated soft ferromagnetic nature sample suggesting can be developed possible shape memory applications.
