20.500.12556/RUL-105930 Detection and characterization of stainless steel SCC by the analysis of crack related acoustic emission In the paper the results of the acoustic emission (AE) based detection and characterization of stress-corrosion cracking (SCC) in stainless steel are presented. As supportive methods for AE interpretation, electrochemical noise, specimen elongation measurements, and digital imaging of the specimen surface were used. Based on the defined qualitative and quantitative time and power spectra characteristics of the AE bursts, a manual and an automatic procedure for the detection of crack related AE bursts were introduced. The results of the analysis of the crack related AE bursts indicate that the AE method is capable of detecting large scale cracks, where, apart from intergranular crack propagation, also some small ductile fractures occur. The sizes of the corresponding ductile fracture areas can be estimated based on a relative comparison of the energies of the detected AE bursts. It has also been shown that AE burst time and power spectra features can be successfully used for the automatic detection of SCC. physics acoustic emission signal processing stress-corrosion cracking spectral analysis fizika ultrazvok akustična emisija korozijsko pokanje spektralna analiza pokanje procesiranje signalov true false true Angleški jezik Slovenski jezik Članek v reviji 2018-12-24 11:41:59 2018-12-24 11:42:00 2025-02-24 12:48:30 0000-00-00 00:00:00 2015 0 0 Str. 312-322 Vol. 62 2015 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2017-06-01 534(045) 0041-624X 10.1016/j.ultras.2015.06.005 14050843 26569728 RAZ_Kovac_Jaka_i2015.pdf RAZ_Kovac_Jaka_i2015.pdf 1 28570B4CD2AAC187D0310784703DD42B 01bbe4ec4b0e46e7b2903114029529a3bce8b61f17310033f9964a23f99e662a 3f19dfd4-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=116651 Fakulteta za strojništvo 0 0 0
