Abstract
Electrical resistivity and magnetic properties on Ni52Mn26Al22 polycrystalline Heusler alloy are investigated in detail. The progress of transformation of this alloy was also followed by heat flux measurements. The transformations were found to be broad and hysteretic. Using Deng & Ansell’s phenomenological theory, the energy consumed for phase boundary motion in this polycrystalline alloy was found to be (31.5 J/mol). The broad transition as compared to Ni–Mn–Ga observed in this polycrystalline alloy, is discussed in light of a phenomenological model.
