Properties and Decomposition of Heusler Alloys Academic Article

abstract

• AbstractMartensitic transformations of rapidly quenched and lessrapidly cooled Heusler alloys of type NiMnX with X=Ga,In,and Sn are investigated by abinitio calculations. For alloys rapidly cooled from 1173K, we obtain the wellknown magnetocaloric properties near the magnetocaloric phase transition. For the lessrapidly cooled alloys with secondary heat treatment these magnetocaloric properties start to change considerably, because each alloy transforms during temperannealing into a dualphase composite alloy. These two phases are identified to be cubic stoichiometric Ni2MnX and tetragonal disordered NiMn.
