Results 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 ...

The Normal State Resistivity of Grain Boundaries in YBa2Cu3O7-delta
, 2003 Using an optimized bridge geometry we have been able to make accurate measurements of the properties of YBa2Cu3O7-delta grain boundaries above Tc. The results show a strong dependence of the change of resistance with temperature on grain boundary angle ...

Role of grain boundary plane in grain boundary engineering
Materials Science and Technology, 2010 There is an increasing amount of interest in grain boundary engineering (GBE) to improve the properties of the grain boundary network. In general, research has concentrated on use of a grain boundary misorientation based approach, namely, the coincidence site lattice (CSL), to categorise ‘special’ boundaries.

Deformation Behavior of La2O3‐Doped Copper during Equal Channel Angular Pressing
Advanced Engineering Materials, EarlyView.By additions of strengthening elements and/or structure optimization, the mechanical properties of copper can be increased while keeping favorable electric conductivity. By combining addition of La2O3 and processing by equal channel angular pressing, substructure development is achieved, leading to increase in microhardness to more than double the ...

Entropy-Driven Grain Boundary Segregation: Prediction of the Phenomenon
Metals, 2021 The question is formulated as to whether entropy-driven grain boundary segregation can exist. Such a phenomenon would be based on the assumption that a solute can segregate at the grain boundary sites that exhibit positive segregation energy (enthalpy ...

Tilt Grain-Boundary Effects in S- and D-Wave Superconductors
, 1998 We calculate the s- and d-wave superconductor order parameter in the vicinity of a tilt grain boundary. We do this self-consistently within the Bogoliubov de Gennes equations, using a realistic microscopic model of the grain boundary.

A multiscale constitutive model for intergranular stress corrosion cracking in type 304 austenitic stainless steel [PDF]
, 2013 Intergranular stress corrosion cracking (IGSCC) is a fracture mechanism in sensitised austenitic stainless steels exposed to critical environments where the intergranular cracks extends along the network of connected susceptible grain boundaries.

Advanced Engineering Materials, EarlyView.This study demonstrates a novel, additive manufacturing approach to produce complex, porous tungsten carbide structures using water‐based direct ink writing/robocasting. Leveraging a modified commercial printer and heat treatment, the process yields lightweight, electrically conductive 3D architectures capable of supporting a mechanical load.
