Suñol Martínez, Joan Josep Khitouni, Mohamed Aliatges amb memòria de forma Shape memory alloys Transformacions martensítiques Martensitic transformations The impact of annealing on the structural and martensitic transformation of Mn50Ni42.5Sn7.5 (at.%) shape memory alloy was systematically investigated using a scanning electron microscope, X-ray diffraction (XRD), and differential scanning calorimetry. Analysis of X-ray diffraction patterns confirms that the as-cast and annealed alloys have martensitic structure at room temperature: seven-layered monoclinic 14M. In addition, it has observed that during annealing, the transition temperatures have increased relative to the cast alloy. Also, a high dependence between the cooling rate and activation energy has detected. A more detailed characterization of martensitic transition and account of thermodynamic parameters were examined after annealing This work was funded by the “Taishan Scholar” Project of Shandong Province and Key Basic Research Project of Shandong Natural Science Foundation of China (no.
