Cantor entropia altuko aleazioaren emisibitate infragorriaren eta egoera mikroestrukturalaren azterketa

Abstract

Entropia altuko aleazioak azken hamarkadan ikerkuntzan hauen propietate bikainak direla eta interes handiahartu duten materialak dira. Propietate termo-optikoen ezagutza ezinbestekoa da material berrien garapenerako,aldiz oraindik ez da aleazio berri hauen horrelako neurketarik egin. Lan honetan Cantor aleazioaren azterketamikroestruktruala egin da alde batetik eta norabidezko emisibitate espektralen neurketa espektro infragorrianbestetik. Honen bidez ikusi da aleazio honen testura kristalografikoak ez duela eraginik emisibitate balioetan.

In the last decade, high entropy alloys have attracted much attention due to their excellent properties.Theknowledge of thermooptic properties is essential for the development of new material, even though there has beenno meassurement of this kind yet. In this work, Cantor alloy’s microstructural analysis and directional spectralemissivity meassurements on the infrared range have been performed. By this the lack of relationship betweencrystalographic texture and and emissivity values has been observed.
