20.500.12556/DKUM-65394 Low temperature impact toughness of the main gas pipeline steel after long-term degradation The correlation of microstructure, temperature and Charpy V-notch impact properties of a steel 17G1S pipeline steel was investigated in this study. Within the concept of physical mesomechanics, the dynamic failure of specimens is represented as a successive process of the loss of shear stability, which takes place at different structural/scale levels of the material. Characteristic stages are analyzed for various modes of failure, moreover, typical levels of loading and oscillation periods, etc. are determined. Relations between low temperature derived through this test, microstructures and Charpy (V-notch) toughness test results are also discussed in this paper. impact toughness fracture damage gas pipeline steel degradation udarna žilavost preizkušanje poškodbe plinovod jeklo razgradnja true false true Angleški jezik Slovenski jezik Znanstveno delo 2017-04-03 14:24:40 2017-04-03 14:27:46 2022-07-08 03:07:58 2019-07-11 13:45:17 2014 0 0 str. 408-415 št. 4 Letn. 4 Dec. 2014 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1896-1541 621.791 5088865 18460950 10.2478/s13531-013-0178-6 1896-1541 URN:SI:UM:DK:HVWNT1OQ Open_Engineering_2014_Maruschak_et_al._Low_temperature_impact_toughness_of_the_main_gas_pipeline_steel_after_long-term_degradation.pdf Open_Engineering_2014_Maruschak_et_al._Low_temperature_impact_toughness_of_the_main_gas_pipeline_steel_after_long-term_degradation.pdf 1 E4A04364D40A7569F82AA542B3714D9D 31ff45711049b7f1259c6ed4f8e491a8dcf2105e645be7d60c799cbb3acd9aaa 0e752547-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=110530 http://www.degruyter.com/view/j/eng.2014.4.issue-4/s13531-013-0178-6/s13531-013-0178-6.xml 1 https://dk.um.si/Dokument.php?lang=slv&id=110529 Fakulteta za strojništvo 0 0 0
