20.500.12556/DKUM-66568 Charpy toughness of vibrated microstructures Charpy žilavost vibriranih mikrostruktura The aim of this study was to investigate the influence of vibration on impact toughness of weld metal. Studies were carried out on two welds, of which one had been welded with applying vibration during welding. From test plates samples were made to simulate heat affect in combination with or without vibration after solidification. In this way conditions at multi-pass welding were simulated. According to different conditions Charpy toughness on non standard specimens and fracture appearance were observed. Vibration during welding benefits impact energy of weld metal, especially if weld metal undergoes further heatb treatment. Namjena ovog članka je istraživanje utjecaja vibriranja na udarnu žilavost zavara. S namjenom istraživanja zavarena su dva zavara s istim parametrima, s tim da je jedan od zavara tijekom procesa zavarivanja bio podvrgnut vibraciji. Iz probnih ploča uzeti su uzorci koji su bili dodatno grijani u peći. Neki uzorci su bili dodatno vibrirani u peći. Tim postupkom simulirano je višeprolazno zavarivanje. Mjerena je Charpy žilavost na nestandardnim uzorcima i analizirani prelomi obzirom na različite uvjete grijanja i vibriranja. Vibracije za vrijeme zavarivanja povećavaju udarnu žilavost zavara, posebno ako je zavar podvrgnut naknadnom toplinskom utjecaju. welded joints impact toughness vibration Charpy toughness SAW zvarni spoji udarna trdnost vibriranje Charpy žilavost EPP true false true Angleški jezik Hrvaški jezik Znanstveno delo 2017-07-03 12:43:53 2017-07-03 12:57:44 2022-08-01 12:55:28 2019-07-11 15:51:46 2005 0 0 str. 103-106 št. 2 Letn. 44 2005 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1334-2576 621.791.6.05:620.178.7 6892802 9369622 1334-2576 URN:SI:UM:DK:AKZ7932W Metalurgija_2005_Gliha_Charpy_Toughness_O_._Vibrated_Microstructures.pdf Metalurgija_2005_Gliha_Charpy_Toughness_O_._Vibrated_Microstructures.pdf 1 4D06B485DF4512496DA523508E4D73EA 22894f6cc7ac2fdb9d7bc87fca0f5c6be745f3aabaf8a810b5a4576663f60a8e 564b5280-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/d0d41d88-aaaf-4962-8fca-5ce3d9e94d76 https://dk.um.si/Dokument.php?lang=slv&id=113480 http://hrcak.srce.hr/127883 1 https://dk.um.si/Dokument.php?lang=slv&id=113482 Fakulteta za strojništvo 0 0 0
