The Effects of Dynamic Load on Behaviour of Welded Joint A-387 Gr. 11 Alloyed Steel
The in-service behaviour of alloyed steel A-387 Gr. 11 Class 1, for pressure vessels, used for high temperature applications, depends on the properties of its welded joint, with parent metal (BM), heat-affected-zone (HAZ) and weld metal (WM) as constituents. Charpy testing of BM, WM and HAZ, together with determination of the parameters of fatigue-crack growth and fatigue threshold Delta_Kth was used, in order to understand, how heterogeneity of structure and different mechanical properties of welded joint constituents affects on crack initiation and propagation.
