Paperback. Etat : new. Paperback. Magnetic shape-memory alloys (MSMAs) are smart materials which show in single crystalline form a magnetic field induced plastic and recoverable deformation of up to 10 %. Ni-Mn-Ga is the as most prominent representative. The shape change of MSMAs is based on the motion of twin boundaries driven by a magneto-stress due to an applied magnetic field. The plastic deformation takes place in the martensite phase and does not require a phase change as needed in shape-memory alloys (SMAs). The combination of high strain of SMAs and high actuation frequencies positions MSMAs as attractive smart actuator materials. Several aspects influence the magneto-mechanical properties. To identify the influence of composition, surface deformation, and constraints separately, this dissertation consists of three parts: first, the characterization of composition, structure, transformation temperatures, magnetic and mechanical properties as a study on position within an ingot. Second, the influence of surface polishing and surface deformation on the twinning stress. Third, the influence of training and constraints on magneto-mechanical properties.It can be shown in this work that each of the investigated aspects has strong influences on i.e. martensite structure and transformation temperatures, twinning stresses, twin microstructure, and magneto-mechanical properties of MSMAs.

Paperback. Etat : new. Paperback. In the contemporary landscape, NITI shape memory alloys are extensively employed across various engineering fields. The impact of Copper on minor additions to the Nickel and Titanium blend, as well as the behavior of the shape memory alloy wire concerning mechanical properties and multiple applications, is critical. The addition of Copper has been found to enhance strength and wear resistance without detriment to the alloys. A small quantity of Copper increases the hardness of the alloy after the Ageing Process. Moreover, a minor addition of Copper in NITI assists in refining grain size and bolstering mechanical properties and workability. This item is printed on demand.

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - This work investigates the influence of inoculants and the directional solidification process on the microstructural and mechanical properties of shape memory Cu-Al-Mn alloys. The alloys were produced by melting in an induction furnace, with controlled addition of inoculant elements, and subjected to directional solidification, followed by appropriate heat treatments. Characterization was carried out using optical microscopy, scanning electron microscopy, X-ray diffraction and ultramicrohardness tests. The results indicate that the addition of inoculants promotes grain refinement and modifies microstructural morphology, while directional solidification contributes to preferential grain orientation and greater structural homogeneity. These changes are reflected in improvements in mechanical properties, especially in the increase in microhardness and in the stability of the martensitic phase associated with the shape memory effect. The results also show that the combination of inoculation and directional solidification is an efficient strategy for optimizing the mechanical and functional performance of Cu-Al-Mn alloys, increasing their potential for technological applications.…
