MOSSBAUER INVESTIGATION OF SOME BCC Fe-BASED, MULTICOMPONENT ALLOYSWojciech Olszewski1, Krzysztof Szymański1, Dariusz Satuła1, Dariusz Oleszak2 1 University of Bialystok, Faculty of Physics, 41 Lipowa Str., 15-424 Białystok, Poland 2 Warsaw University of Technology, Department of Materials Science and Engineering, 141 Wołoska Str., 02-507 Warsaw, Poland Mössbauer measurements of a Fe-based, bcc multicomponent alloys with concentration of non-ferrous element x = (0.1, 0.3 and 0.6) were performed. The effective thickness parameters and the second order Doppler shifts were determined as a function of temperature. The results indicate an apparent decrease of the recoilless fraction with x. The observed trends are consistent with theoretical results indicating modifications of phonon density of states by bond disorder. Close X |
