Hydrogen-induced Cracking in Pure Iron
The modulus and internal friction of Armco iron rere continuously measured during cathodic charging rith hydtogen to investigate crack initiation and grorth. The observed modulus decrease ras attributed to crack initiation and grorth. The internal friction increase doring cathodic charging ras atfributed to plastic deformation accompanying the crack formation. Both the modulos and internal fric...
متن کاملThe Effect of Hydrogen Content and Welding Conditions on the Hydrogen Induced Cracking of the API X70 Steel Weld
In this study, first,diffusible hydrogen of cellulosic electrode E8010-P1 and low hydrogen electrode E8018-G was measured by mercury displacement method according to ISO3690. Then,the effect of preheating and post-heating on the sensitivity to hydrogen inducedcold cracking in welding of 18mm API5L X70 steel with these electrodes was investigated according to ISO17642-2. The results of visual in...

the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
15 صفحه اولInfluence of S Contents on the Hydrogen Blistering and Hydrogen Induced Cracking of A350LF2 Steel
In the present work, the effects of chemical compositions on the hydrogen blistering and hydrogen induced cracking of A350LF2 steel with different S contents were studied. Four types of A350LF2 steels were evaluated by immersing samples in H2S-saturated NACE solution. The hydrogen blistering, crack length rate(CLR), crack thickness rate(CTR) and crack sensitivity rate(CSR) were evaluated. The r...
