WebJan 1, 2024 · In the current paper, high-temperature creep behaviors of T91 and T92 steels have been investigated. Creep tests were performed for both steels at varied temperatures. The creep mechanisms of T91 and T92 steels were elucidated by analyzing the creep rupture data of the two steels. In addition, Manson-Haferd model was employed to predict … WebJan 14, 2024 · Creep and Deformation of Metals and Alloys at Elevated Temperatures Article Full-text available Nov 2024 Nadezhda Dudova View Show abstract Effectiveness of Ni-based and Fe-based cladding... share price bld
