Three magnetic shape memory alloys: Mn50Ni50-x Sn x (x = 5, 7.5, and 10) were produced as bulk polycrystalline ingots by arc melting. The structural austenite-martensite transformation was checked by calorimetry. The transformation temperatures decrease as increasing the Sn content. The same trend is found in the entropy and enthalpy changes related to the transformation. The control of the valence electron by atom e/a determines the transformation temperatures range in this kind of alloys and it is possible to develop alloys that can be candidates in applications as sensors and actuators. Furthermore, X-ray diffraction was performed to check the crystalline structure at room temperature FICYT is acknowledged by J.L.S.LL (COF07-013). This study has been supported by the Spanish MEC under projects MAT2006-13925-C02-01 and MAT2006-13925-C02-02 |
