20.500.12556/RUL-133388 Mechanisms of oxidation degradation of Cr12 roller steel during thermal fatigue tests Degradation by the penetration of oxidation into the Cr12 roller steel is evaluated during thermal fatigue tests in the laboratory in the temperature range of 500–700 °C. A qualitative assessment is carried out with regard to the thermal load, the microstructure and the test temperature. The results show that the specific properties of the microstructure with respect to thermal stress and temperature have a significant influence on the oxidation behavior as well as on the crack propagation mode and crack growth. The conditions that lead to an increase in the oxidation rate and thus to premature and sudden local chipping of the roll surface layer are analyzed and explained. steel thermal cycling oxidation interfaces effects of strain true false true Angleški jezik Ni določen Članek v reviji 2021-11-25 08:00:25 2021-11-25 08:00:26 2022-09-12 04:16:06 0000-00-00 00:00:00 2020 0 0 27 str. iss. 4, art. 450 Vol. 10 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 669 2075-4701 10.3390/met10040450 1859423 RAZ_Bombac_David_2020.pdf RAZ_Bombac_David_2020.pdf 1 113FF04E06CD61780C8AB4C53E9B83C1 d2bdc92160c5a50f637d7417eb1b02ba40246f3473a04f6a3edae6e4fe41c6af 880fd207-4dbd-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=151415 https://www.mdpi.com/2075-4701/10/4/450 0 7e07eeea-4dbd-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=151414 Naravoslovnotehniška fakulteta 0 0 0
