Modeling study of mesoscale magnetic treatment influencing factors through dynamic softening analysis

open access: yesResults in Physics, 2023
In this paper, a new concept of “dynamic softening” is proposed to explain the mechanism of residual stress reduction through “cold” treatment. The impact of grain size, grain boundary width, and grain orientation on the reduction was studied through ...

Forming incoherent twin boundaries: a new way for nanograin growth under cyclic loading

open access: yesMaterials Research Letters, 2017
Obvious grain growth was observed in regions around the fatigue cracks in the Au thin films under cyclic loading. Dominant generation of twin boundaries (TBs) and low-angle grain boundaries was observed in the coarsened grains.

Data Pipeline Development for Grain Boundary Structures Classification [PDF]

open access: yesarXiv, 2017
Grain Boundaries govern many properties of polycrystalline materials, including the vast majority of engineering materials. Evolutionary algorithm can be applied to predict the grain boundary structures in different systems. However, the recognition and classification of thousands of predicted structures is a very challenging work for eye detection in ...

A novel level-set finite element formulation for grain growth with heterogeneous grain boundary energies

open access: yesMaterials & Design, 2018
Grain growth is a ubiquitous thermally activated mechanism by which the microstructures of crystalline materials coarsen at relatively high temperatures.

Enhanced mechanical performance of fusion zone in laser beam welding joint of molybdenum alloy due to solid carburizing

open access: yesMaterials & Design, 2019
It is unable to strengthen molybdenum (Mo) through solid-state phase transformation, while exploring the effect of carbon (C) on microstructures and properties of fusion zone (FZ) of laser beam welding (LBW) joints of Mo alloy with serious grain boundary

Kinetic and Equilibrium Shapes of Cylindrical Grain Boundaries [PDF]

open access: yesarXiv
In this work, we investigate the shape evolution of rotated, embedded, initially cylindrical grains (with [001] cylinder axis) in Ni under an applied synthetic driving force via molecular dynamics simulations and a continuum, disconnection-based grain boundary migration model.
