20.500.12556/DKUM-67228 Deformation and energy parameters of fracture of steel of the main gas pipeline By example of steel 17G1S, the regularities in the impact fracture of Charpy specimens at normal and low temperatures are described. The relationship between the energy parameters of fracture (impact toughness) and the deformation response of the material (the height of shear lips) of the specimens from the pipe steel is established. The micromechanisms of impact fracture of the material are described. At 20 °C and –30 °C, focal splitting of the material was observed on the fracture surface of specimens; at –60 °C, the material failed in a brittle manner by the mechanism of cleavage. impact toughness main gas pipeline failure analysis žilavost udar glavni plinovod analiza napak true false true Angleški jezik Slovenski jezik Znanstveno delo 2017-08-08 09:33:53 2017-08-08 09:35:03 2022-08-01 13:42:23 2019-07-11 16:13:13 2015 0 0 str. 40-46 št. 28 Letn. 9 2015 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2080-4075 524607513 10.12913/22998624/60781 2080-4075 URN:SI:UM:DK:1XVU5HAE Advances_in_Science_and_Technology-Research_Journal_2015_Maruschak_et_al._Deformation_and_Energy_Parameters_of_Fracture_of_Steel_of_the.pdf Advances_in_Science_and_Technology-Research_Journal_2015_Maruschak_et_al._Deformation_and_Energy_Parameters_of_Fracture_of_Steel_of_the.pdf 1 69ACB63537CB89F4E8EA9CB6BE8D20C0 e9b877e7c813bada6dbe1c00a6c4bfe32df27a9b58cc53915a6c800b98a22281 7dad1849-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/346756a5-c2df-4a6e-85de-c1319880edc7 https://dk.um.si/Dokument.php?lang=slv&id=114981 http://www.journalssystem.com/astrj/DEFORMATION-AND-ENERGY-PARAMETERS-OF-FRACTURE-OF-STEEL-IN-THE-MAIN-GAS-PIPELINE,60781,0,2.html 1 https://dk.um.si/Dokument.php?lang=slv&id=114980 Fakulteta za strojništvo 0 0 0
