Journal ArticleDOI
On the validity of the hall-petch relationship in nanocrystalline materials
TL;DR: In this paper, a study experimentale de la variation de la durete en fonction de la grosseur de grain for des materiaux nanocristallins is presented.
Journal ArticleDOI
Superplasticity in advanced materials
TL;DR: A review of superplasticity in polycrystalline materials can be found in this article, where the authors present an overview of these new developments using the established behavior of conventional metallic alloys as a standard for comparison with the mechanical properties of new materials.
Journal ArticleDOI
Dynamic recrystallization in high-strain, high-strain-rate plastic deformation of copper
TL;DR: In this paper, it is proposed that this microstructure develops by dynamic recrystallization, which is enabled by the adiabatic temperature rise, and the grain size-flow stress relationship observed after cessation of plastic deformation is consistent with the general formulation proposed by Derby (Acta metall, mater. 39, 955 (1991)).
Journal ArticleDOI
The effect of grain size on the high-strain, high-strain-rate behavior of copper
TL;DR: In this paper, it was shown that the grain-size dependence of shock response can significantly affect the performance of shaped charges, leading to a prediction of the shock threshold stress for twinning as a function of grain size.
Journal ArticleDOI
A Huge Effect of Weak dc Electrical Fields on Grain Growth in Zirconia
Santonu Ghosh,Santonu Ghosh,Atul H. Chokshi,Atul H. Chokshi,Pilhwa Lee,Pilhwa Lee,Rishi Raj,Rishi Raj +7 more
TL;DR: In this paper, the authors show that the application of a modest dc electrical field, about 4 V/cm, can significantly reduce grain growth in yttria-stabilized polycrystalline zirconia.
