Ib qho piv txwv ntawm brittle alloy yog cam khwb cia hlau. Hydrogen embrittlement yog ib qho tshwm sim los ntawm hydrogen atoms diffusing mus rau hauv lub micro-structure ntawm ib tug hlau ua rau nws ua nkig ntau, ua rau tam sim ntawd thiab unpredictable puas (hydrogen induced cracking).
Dab tsi ua rau hydrogen embrittlement hauv steel?
Hydrogen Embrittlement tshwm sim thaum cov hlau ua nkig vim qhov kev taw qhia thiab nthuav tawm ntawm hydrogen rau hauv cov khoom. Qib ntawm embrittlement yog cuam tshuam los ntawm tus nqi ntawm hydrogen absorbed thiab microstructure ntawm cov khoom.
Koj paub li cas hydrogen embrittlement?
Kev sim khoov yooj yim feem ntau yog siv los kuaj pom muaj hydrogen embrittlement. Met-allographic cov tswv yim (Daim duab 4) kuj tseem siv tau los saib qhov ze ze ntawm qhov chaw thiab rau qhov muaj cov voids ntawm cov ciam teb.
Yuav ua li cas hydrogen de embrittlement txheej txheem?
De-embrittlement yog txheej txheem ntawm cov hlau tawv, tshwj xeeb yog cov hlau tsis muaj zog hydrogen uas tau tsis txhob txwm qhia rau hydrogen. Qhov kev raug hydrogen no ua rau cov hlau nkig thiab tawg; kev puas tsuaj rau cov hlau muaj zog thiab lwm yam hlau siv.
Puas stainless hlau raug kev txom nyem los ntawm hydrogen embrittlement?
Annealed hom 304 stainless hlau is susceptible to hydrogen embrittlement in nro, Table 3.1.1.1. … Hydrogen muaj qhov cuam tshuam tsis zoo rau kev tawm dag zog ntawm hom 304 stainless hlau uas tsis muaj martensite thiab carbide nag lossis daus, tab sis me ntsis txo lub zog qhov kawg.
