20.500.12556/DKUM-66575 Internal oxidation of silver alloys with tellurium, selenium and sulphur Unutarnja oksidacija legura srebra s telurom, selenom i sumporom Silver alloys with tellurium, selenium and sulphur fulfil the conditions for the internal oxidation. Microstructure of these alloys consists of matrix (dilute solid solution) and particles of intermetallic compounds. Internal oxidation of ternary alloys is very similar to that of the binary alloys, but there are also distinctions in thermodynamics properties of alloying elements. At the direct oxidation of the particles of the intermetallic compound the phenomena of the selective oxidation was observed. Concentration of more reactive elements is increasing in the oxidized part of the particles of the intermetallic compound (Te in AgTeSe alloys). Therefore the precipitated oxides formed with diffusional internal oxidation are richer with less reactive alloying element (Se in AgTeSe alloy). In the precipitated oxide particles the concentration of selenium is more than twice higher than of tellurium. Legure srebra s telurom, selenom i sumporom ispunjavaju uvjete za unutarnju oksidaciju. Mirkostruktura ovih legura sastoji se od osnove (razrijeđena kruta otopina) i čestica intermetalnih spojeva. Unutarnja oksidacija ternarnih legura veoma je slična onoj za binarne legure, ali postoje i razlike u termodinamičkim svojstvima legirajućih elemenata. Kod izravne oksidacije čestica intermetalnog spoja zapažena je pojava selektivne oksidacije. Koncentracija reaktivnijih elemenata raste u oksidiranom dijelu čestica intermentalnog spoja (Te u AgTeSe leguri). Prema tome precipitirani oksidi nastali difuzijskom unutarnjom oksidacijom su bogati s manje reaktivnim legirajućim elementom (Se u AgTeSe leguri). U percipitiranim oksidnim česticama koncentracija selena je dvostruko veća nego telura. internal oxidation silver alloys compound particle notranja oksidacija srebro zlitine sestavljanje drobci true false true Angleški jezik Slovenski jezik Znanstveno delo 2017-07-03 13:32:27 2017-07-03 13:33:21 2022-08-01 12:55:56 2019-07-11 15:51:59 2005 0 0 str. 37-39 št. 1 Letn. 44 2005 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1334-2576 669 524301593 521311 1334-2576 URN:SI:UM:DK:1EWVLRNX Metalurgija_2005_Kosec_et_al._Internal_oxidation_of_silver_alloys_with_tellurium,_selenium_and_sulphur.pdf Metalurgija_2005_Kosec_et_al._Internal_oxidation_of_silver_alloys_with_tellurium,_selenium_and_sulphur.pdf 1 4AEA9B2ABEC3D6B6F95A74A95B0CB2F1 de6b541766ab1b66319a120eb144dbf5c2f1f93fdd67b2f938cf308f157cca95 56d0daf1-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/8fb129f2-7f78-4596-a4d9-b1463f1946a1 https://dk.um.si/Dokument.php?lang=slv&id=113497 http://hrcak.srce.hr/127945 1 https://dk.um.si/Dokument.php?lang=slv&id=113496 Fakulteta za strojništvo 0 0 0
