In most cases, materials are developed to improve their most frequently used properties, but some of these materials also exhibit specific properties which make them useful in a wide variety of applications. An example are the shape-memory materials, which, under the influence of temperature changes, are capable of changing their shape and producing work. In this paper the specific properties of shape-memory materials and the advantages and disadvantages of using these materials in practical applications are discussedNovi materiali omogočajo v strojništvu doseganje ciljev, ki do odkritja teh materialov niso bili uresničljivi. Razvoj materialov se usmerja predvsem k izboljševanju najpogosteje zahtevanih lastnosti, nekateri materiali pa izkazujejo določene posebnosti zaradi katerih je področje njihove uporabe še posebej široko. Med slednje spadajo tudi materiali z oblikovnim spominom, ki so pod vplivom temperaturnih sprememb zmožni spreminjati obliko in pri tem tudi opravljati delo. V prispevku so opisane posebnosti teh materialov ter njihove prednosti in pomanjkljivosti pri uporabi za praktične primereTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
