WebNov 6, 2024 · In shape memory materials the fine twinned microstructure plays a fundamental role. Here we show that in the martensite phase of Ni-Mn-Ga Heusler alloy, the fine features of electronic structure are not caused by intrinsic electronic changes but mesoscopically different orientations of ferroelastic domains, i.e., twins. The cuts of … Weblike ferrite and twinned martensite [1{3] di er greatly.
