20.500.12556/RUL-126687 Effects of surface finish and mechanical training on Ni-Ti sheets for elastocaloric cooling Elastocaloric cooling has emerged as a promising alternative to vapor compression in recent years. Although the technology has the potential to be more e ffi cient than current technologies, there are many technical challenges that must be overcome to realize devices with high performance and acceptable durability. We study the e ff ects of surface finish and training techniques on dog bone shaped polycrystalline samples of NiTi. The fatigue life of several samples with four di ff erent surface finishes was measured and it was shown that a smooth surface, especially at the edges, greatly improved fatigue life. The e ff ects of training both on the structure of the materials and the thermal response to an applied strain was studied. The load profile for the first few cycles was shown to change the thermal response to strain, the structure of the material at failure while the final structure of the material was weakly influenced by the surface finish. elastocaloric effect surface finish colling fatigue life shape memory material elastokalorični efekt kvaliteta površine hlajenje doba trajanja material z oblikovnim spominom true false true Angleški jezik Slovenski jezik Članek v reviji 2021-05-04 13:39:05 2021-05-04 13:39:08 2025-03-14 11:43:53 0000-00-00 00:00:00 2016 0 0 Str.. 1-6 iss. 6, art. 064110 Vol. 4 2016 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 2016-06-17 2016-06-28 621.565.91(045) 2166-532X 10.1063/1.4955131 14774555 RAZ_Engelbrecht_Kurt_2016.pdf RAZ_Engelbrecht_Kurt_2016.pdf 1 044A45442E0A1F0BDC7B84F36A05EFB2 ecb92fd73650a31032f4dfdc4ae65ef49706e7f7f0d7d294c2f45dabfeb29f47 4f1b73f7-accf-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=142745 http://scitation.aip.org/content/aip/journal/aplmater/4/6/10.1063/1.4955131 1 538a86e8-accd-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=142742 Fakulteta za strojništvo 0 0 0
