Effect of misorientation of grain boundaries on the discontinuous precipitates of Cu–Ni–Si alloy

Journal of Materials Research and Technology, 2023
In this study, the effects of differences in grain size, grain boundary type and misorientation on the initiation of discontinuous precipitates are investigated for the Cu–5Ni–1.25Si alloy.

High-entropy grain boundaries

Communications Materials, 2023
High-entropy materials are defined by the configurational entropy of their bulk phase, yet it is interesting to consider whether grain boundaries can also be “high entropy”.

Microevolution of grain boundary character distribution in Hastelloy C-276 during the annealing process

Journal of Materials Research and Technology, 2022
Grain boundary character distribution and disconnectivity of random boundaries were observed “in-situ” in the Hastelloy C-276 alloy sample through thermomechanical processing.

Grain Boundary Shear Coupling is Not a Grain Boundary Property [PDF]

SSRN Electronic Journal, 2018
Shear coupling implies that all grain boundary (GB) migration necessarily creates mechanical stresses/strains and is a key component to the evolution of all polycrystalline microstructures. We present MD simulation data and theoretical analyses that demonstrate the GB shear coupling is not an intrinsic GB property, but rather strongly depends on the ...

Effect of symmetrical 〈001〉 tilt grain boundaries on the indentation induced plastic deformations of diamond

Materials & Design, 2021
Although nanostructuring strategies can greatly enhance the hardness of diamond, a large amount of grain boundaries were involved, and little research has been reported on the effect of grain boundaries on the indentation hardness and plastic deformation

Phase-field modeling of interaction between void and grain boundaries and its swelling effect

AIP Advances, 2023
The interaction of irradiated voids and grain boundaries in zirconium is systematically studied by using a composite multiphase-field model that couples the evolution of irradiated voids and grain boundaries.

The Effect of B on the Co-Segregation of C-Cr at Grain Boundaries in Austenitic Steels

Metals, 2023
In austenitic steels, the co-segregation of C and Cr at grain boundaries can result in the formation of Cr23C6. However, the addition of B to steels can effectively reduce the amount of Cr23C6 formed and inhibit its ripening in experiments ...
