The newly developed TMW disk superalloy exhibits better overall mechanical properties in the intended service temperature region (650-750 °C) than the most advanced cast & wrought disk alloy U720Li. Clarification of the underlying mechanisms is beneficial for designing advanced superalloys. Among the TMW alloys, TMW-4M3 has the best tensile strength and creep resistance. In this study, tensile ...
The formation mechanism considers fivefold deformation twins originating from the grain boundaries in a nanocrystalline material, resulting in that fivefold deformation twins derived from a single crystal have not been reported by molecular dynamics simulations. In this study, fivefold deformation twins are observed in a single crystal of face-centered cubic (fcc) alloy. A new formation mechani...
Although deformation processes in submicron-sized metallic crystals are well documented, the direct observation of deformation mechanisms in crystals with dimensions below the sub-10-nm range is currently lacking. Here, through in situ high-resolution transmission electron microscopy (HRTEM) observations, we show that (1) in sharp contrast to what happens in bulk materials, in which plasticity ...
