MICRO-MACRO DAMAGE SIMULATION OF LOW-ALLOY STEEL WELDS SUBJECT TO TYPE IV CREEP FAILURE T.Igari1,T.Tokiyoshi1,N.Tada2,F.Kawashima1 (1.Nagasaki R&D Center, Mitsubishi Heavy Industries, Ltd., Nagasaki 851-0392, Japan;2.Faculty of Engineering, Okayama University, Okayama 700-8530, Japan) Abstract:A simulation method for microscopic creep damage at grain boundaries in the finegrain heat-affected......
Creep Behaviors of DA Casting and Rolling GH4169 Superalloy () 摘要:After the billet of Casting and Rolling GH4169 alloy was directly aged (DA) treated at 720℃ and 620℃, creep behavior and deformed features of the alloy were investigated by means of the measurement of creep curves and microstructure observation. Results show that the DA Casting and Rolling GH4169 Superalloy displays a lower......
