Mismatch effect in creep properties on creep crack growth Creep Crack Growth Properties of P91 Parent and Welded

Nov 01, 20141. Introduction. Most problems of crack initiation and propagation in high temperature components are likely to originate from welded joints , which is caused by the multi stress and strain fields appearing ahead of crack-tip or near the interface of weldment constituents due to the mismatch in creep deformation properties among base metal (BM), weld metal (WM) and heat affected zone Prediction of creep crack growth properties of P91 parent Creep Crack Growth Properties of P91 Parent and Welded Oct 01, 2010In a similar investigation , CCG tests were performed on the internally pressurised seam-welded pipe manufactured from P91 containing artificial axial crack-like flaws in different positions (Parent and HAZ).The CCG rate data was assessed in terms of both stress intensity factor and C .When using C , the assessment of CCG was found to be relatively independent of the stress state and the Creep Crack Growth Properties of P91 Parent and Welded Prediction of creep crack growth properties of P91 parent Creep Crack Growth Properties of P91 Parent and Welded Prediction of creep crack growth properties of P91 parent and welded steel using remaining failure strain criteria Article in Engineering Fracture Mechanics 77(15):3035-3042 October 2010 with Creep Crack Growth Properties of P91 Parent and Welded
