20.500.12556/DKUM-27438 In-situ monitoring of internal oxidation of dillute alloys This paper presents a non-destructive measurement method that enables identification and characterization of phenomena during internal oxidation of metallic materials as well as monitoring the kinetics of internal oxidation using "in-situ" electrical resistance measurements. A special laboratory device, based on the unique measurement cell, for the electrical resistance measurements at high temperatures and the model for electrical resistance transformation into an instantaneous microstructure were developed. To accomplish this, the process of internal oxidation was divided into the sequence of the key partial reactions that were presented in the model as the parallel andžor serial connected time variable resistors in the electrical circuit. The validity of the transformation model was experimentally confirmedby internal oxidation of Ag-Sn (2 at.% Sn) alloy at different oxidation temperatures in air atmosphere. The comparison of the results obtained by "in-situ" electrical resistance measurements with those obtained by metallographic analysis and Wagnerćs theory shows that the novel method presents a more effective tool for monitoring of internal oxidation kinetics. The method identifies also the microstructural defects and their influences onthe kinetics of internal oxidation. metallurgy Ag-Sn alloy internal oxidation electrical resistance metalurgija zlitina Ag-Sn notranja oksidacija električna upornost true false false Angleški jezik Angleški jezik Neznano 2012-06-01 11:14:13 2012-06-01 11:14:13 2022-04-15 03:44:27 2019-07-10 12:17:04 2007 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 669 10702870 0010-938X URN:SI:UM:DK:AM880BOT http://dx.doi.org/10.1016/j.corsci.2006.06.031 1 https://dk.um.si/Dokument.php?lang=slv&id=36738 Fakulteta za strojništvo 0 0 0
