【 摘 要 】

Shape memory alloys are materials with the functionality controlled by a temperature change that leads to a reversible transformation from austenite into martensite. When magnetic field can also be used to influence the functionality, either by magnetic induced transformation or by magnetic induced reorientation. Each of mechanism is analyzed in the paper and their prevalence in the ferromagnetic shape memory alloy systems is discussed. FePd alloys manufactured by arc melting are characterized in the as cast, wire drawn and heat treatment state in view of their integration into functional applications with thermal and magnetic control of the actuation. Structural and microstructural analysis is used to assess the particularities of this alloys in view of their integration into sensor and actuator-based applications.
