Abstract
Legure s prisjetljivosti oblika (SMA) karakteriziraju dva bitna efekta, psudoelastičnost i efekt prisjetljivosti oblika, koji su posljedica austenitno-martenzitne fazne transformacije. Općenito, efekt prisjetljivosti oblika označava sposobnost materijala da se uslijed djelovanja temperature ili mehaničkog naprezanja vraća u svoj prethodno definirani oblik. Temperatura transformacije SMA legura određuje područje primjene ovih materijala te se variranjem udjela komponenti u leguri može korigirati temperatura transformacije, kao i dizajnirati finalna svojstva materijala za specifična područja primjene. Mikrostrukturna ispitivanja, kojima se prati razvoj martenzita, provode se svjetlosnom mikroskopijom (OM) ili skenirajućom elektronskom mikroskopijom (SEM). Kako bi se ispitala toplinska svojstva SMA legura i odredile temperature transformacije, koriste se metode toplinske analize poput diferencijalne pretražne kalorimetrije (DSC), dilatometrije (DIL) te dinamičko-mehaničke analize (DMA).
Abstract (english)
Shape memory alloys (SMA) show two unique efffects, pseudoelasticity and shape memory effect, which are consequenceof austenitic-martensitic phase transformations. Shape memory effect describes the effect of restoring the original shape under thermal changes or plastic deformation. Martensitic transformation temperatures define application area of SMA alloys, and it is strongly influenced by chemical composition of SMA alloys as well as final properties of material. Microstructure investigations and martensitic formation can be followed by optical microscopy (OM) and scanning electron microscopy (SEM). Thermal properties and transformation temperatures can be determind by thermal analysis techiques, such as differential scanning calorimetry (DSC), dilatometry (DIL) and dynamic-mechanical analysis (DMA).
