20.500.12556/DKUM-66586 The microstructure and properties of materials at the fusion line Mikrostruktura i svojstva materijala uz crtu taljenja In this paper, the formation of the HAZ that is caused by the thermal effects of welding is investigated from the theoretical and experimental points of view. Samples of the material found at the fusion line were prepared by simulating the thermal regimes that occur during welding. A number of CCT diagrams that are valid for the conditions during welding were designed, and the hardness and impact-toughness of the samples were measured. This information was then related to the results of metallographic examinations. The maximum temperature and the cooling rate of the applied thermal cycles were found to be decisive in terms of the properties of HAZ. U ovom članku je sa teorijskog i eksperimentalnog motrišta istraživano ustrojstvo zone utjecaja topline (ZUT-a) koji je prouzrokovan termičkim utjecajima zavarivanja. Uzorci materijala, koji se nalazi uz crtu taljenja, bili su pripremljeni simulacijom termičkog postupka za vrijeme zavarivanja. Ustrojeno je više CCT dijagrama, koji važe za uvjete zavarivanja, a mjereni su takođe i tvrdoća te žilavost uzorka. Ti podaci su zatim uspoređeni sa rezultatima metalografskih ispitivanja. Obzirom na svojstva ZUT odlučujući su najviša temperatura primjenjenih termičkih ciklusa i brzina hlađenja. welding HAZ thermal cycle cooling rate fusion line varjenje TVP termični cikel hitrost ohlajevanja talilna črta true false true Angleški jezik Hrvaški jezik Znanstveno delo 2017-07-03 17:39:27 2017-07-03 17:41:24 2022-08-01 12:56:40 2019-07-11 15:52:20 2005 0 0 str. 13-18 št. 1 Letn. 44 2005 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1334-2576 621.791.025:620.181.4 524301593 9119766 1334-2576 URN:SI:UM:DK:IUNSBSW3 Metalurgija_2005_Gliha_the_Microstructure_and_Properties_Of_Materials_At_the_FUsion_Line.pdf Metalurgija_2005_Gliha_the_Microstructure_and_Properties_Of_Materials_At_the_FUsion_Line.pdf 1 8AA2C7610C88C244E3CEE1FAE3FC0221 3820ebb8e56f23230f11a8c13f5fcc2c45c42efc104c3f9ff5e959ceb4152b9a 57b5cf39-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/f94a713c-f898-4476-93c8-bf3d5ba3d70e https://dk.um.si/Dokument.php?lang=slv&id=113524 http://hrcak.srce.hr/127941 1 https://dk.um.si/Dokument.php?lang=slv&id=113523 Fakulteta za strojništvo 0 0 0
