Studi tentang smart materials cukup menyita perhatian dalam beberapa tahun terakhir, salah satunya yaitu tentang Shape Memory Alloys (SMA). Banyak penelitian yang telah dilakukan untuk mengembangkan SMA menggunakan paduan Ni-Ti, namun karena paduan terseb... see more

Quaternary Ni50FexMn30-xGa20 (x = 2.5, 5, and 15) and Ni45Fe5Mn30Ga20 alloys based on modification of ferromagnetic shape memory alloy ternary Ni50Mn30Ga20 composition prepared by vacuum arc melting and subsequent heat-treatment were investigated to under... see more

Ferromagnetic shape memory Ni50Mn30Ga15Al5-xBx (x = 0, 1, and 4) alloys were prepared by vacuum arc melting and subsequent heat-treatment as well as by melt spinning to investigate the effect of trivalent element additions in ternary Ni-Mn-Ga alloys. The ... see more

The cobalt alloys (close to the CoNiAl stoichiometry) are the less known shape memory alloys. Such behavior is consequence of the martensitic transformation. The pseudoelasticity is caused by the stress-induced martensitic transformation above the equilib... see more

Shape memory alloys (SMAs) are metal alloys with a reversible ability to recover their shape at a certain temperature after being deformed. This ability referred to as Shape Memory Effect (SME). The application of SMAs such as Ni-Ti and Cu-Zn-Al alloys us... see more

Heusler type alloys Ni50Mn25+xGa25-x  (x=2,3,4 and 5) based on near stoichiometric Ni2MnGa compositions were directionally solidified using modified Bridgman method. The alloys thus prepared were characterized for their chemical composition, crystal ... see more

Ni–Mn–Ga polycrystalline alloy fibers with diameters of 33 µm are reported to exhibit significantly improved ductility and huge superelastic and shape memory strains in comparison to conventional brittle bulk polycrystalline alloys. Particularly, the reco... see more

Durante los últimos años se ha extendido exponencialmente el uso de aleaciones con memoria de forma en base hierro en el sector de la construcción, especialmente en rehabilitación en países de centro-Europa. Este innovador material se puede usar como pret... see more

Titanium-Platinum (TiPt) has a martensitic transformation of about 1300 K, making it potential material for use as a high-temperature shape memory alloy. A third element is expected to improve the properties of TiPt alloys for future use in the aerospace ... see more
