Mechanisms and anisotropy of serrated flow in Mg–Gd single crystals
Journal of Magnesium and Alloys, 2023 Serrated flow has been primarily studied at the macron scale, yet the length and times scales at which the solute–meditated dislocation pinning and de-pinning processes that underlie the phenomenon occur are largely inaccessible by macroscopic tests ...

Metals, 2020 High-entropy alloys (HEAs) are a novel class of alloys that have many desirable properties. The serrated flow that occurs in high-entropy alloys during mechanical deformation is an important phenomenon since it can lead to significant changes in the ...

Serrated flow behaviors in a Ni-based superalloy
Materials Research Express, 2021 Serrated flow behaviors in Ni-20Cr-18W alloy were studied under different deformation conditions. It was found that there are no serrations observed on the tensile curves of the alloy at the temperature of lower than 250 °C and the strain rate of 10 ^−3 ...
