Piping and components made of nickel alloys under plant specific loading conditions were tested to ensure the feasibility of high‐efficiency ultra‐supercritical coal‐fired power plants by using the test loop HWT II system ( H ochtemperatur‐ W erkstoff‐ T eststrecke) installed in the fossil power plant GKM in Mannheim, Germany. The performance of the materials and the applicability of advanced numerical simulations for the lifetime assessment of components were performed. The results of materials investigations on Alloy 617 mod., Alloy 263, and their welded joints as well as numerical simulations for selected components under static and cyclic loading are presented.
