Effect of prestrain on the microstructure and corrosion resistance of 840 nickel-based alloy

Journal of Materials Research and Technology
The microstructure, grain size, dislocation density, and crystal texture of a material vary owing to prestraining due to external forces. These changes directly affect the corrosion behavior of the material, thereby affecting the structural integrity and

Investigation of the mechanism of the indentation size effect for titanium

Mechanical Engineering Journal, 2019
In this study, we investigated the mechanism of the indentation size effect for Ti, whose crystal structure is hexagonal close-packed. Indentation tests were performed for two types of single-crystal Ti with different crystal orientations: (0001) and ...

Mechanical properties, microstructure, and texture evolution of copper sheets subjected to differential speed rolling process

Materials Research Express, 2022
Copper sheets were subjected to differential speed rolling (DSR) at roll speed ratios (RSRs) from 1 to 3. The effects of the RSR on the yield strength, uniform strain, microstructure, and texture evolution in the copper sheets were investigated.

Elemental partitioning as a route to decrease HAZ hardness

Journal of Materials Research and Technology, 2023
In the present study, in order to find out a valuable method to decrease the hardness of heat-affected zone (HAZ), elemental partitioning was introduced before welding simulation to realize elemental redistribution. The results demonstrate that about 10%

Scaling in Plasticity-Induced Cell-Boundary Microstructure: Fragmentation and Rotational Diffusion

, 2003
We develop a simple computational model for cell boundary evolution in plastic deformation. We study the cell boundary size distribution and cell boundary misorientation distribution that experimentally have been found to have scaling forms that are ...

Charge‐Induced Morphing Gels for Bioinspired Actuation

Advanced Functional Materials, EarlyView.
This study introduces a novel electroactive actuation mechanism that enables the gel material to generate substantial and reversible shape‐changing while preserving topological and isochoric (volumetric) equivalence. The resultant morphing behaviors can mimic the movements of muscle‐driven organelles in nature, including cilia‐like beating and ...

Effect of service temperature on cyclic mechanical behavior of magnesium with fine grained structure

Journal of Materials Research and Technology
To explore the effect of operational service temperatures on the fatigue properties of fine-grained magnesium, we processed magnesium using multi-pass rolling at about 200oC and then tested the samples under a cyclic tension-tension loading at various ...
