Napetostno pokanje jekla NIOMOL 490 K v medijih petrokemije : magistrsko deloGodec, Boštjan, 1961-Preiskave so bile zastavljene na osnovi dejstva, da vodikovo napetosno pokanje povzroča atomski vodik, ki se ujame na določene pasti v materialu. Izhajamo iz predpostavke, da je jeklo, ki ima več ... pasti in predvsem take z večjo interakcijo za vodik, v prisotnosti vodika bolj dovzetno za krhko pokanje. Raziskave odpornosti mikrolegiranega jekla NIOMOL 490K na vodikovo napetosno pokanje so bile narejene v primerjavi z mikrolegiranim jeklom NIOVAL 47 in navadnim konstrukcijskim jekom Č.0562 glede delovanja ujetega notranjega atomskega vodika, ki smo ga ustvarili s katodno polarizacijo pri sobni temperaturi v 1N ▫$H_2SO_4, ki vsebuje 10 mg/As_2_0_3, pri istočasni statični obremenitvi 60% od napetostnega tečenja. Vzporedno s tem je bila narejena preiskava po NACE testu (TM-01-077), ki nam je služila kot potrditev rezultatov.$▫Type of material - master's thesisPublication and manufacture - Ljubljana : [B.
