Journal ArticleDOI
Toward a quantitative understanding of mechanical behavior of nanocrystalline metals
TL;DR: A brief overview of the recent progress made in improving mechanical properties of nanocrystalline materials, and in quantitatively and mechanistically understanding the underlying mechanisms is presented in this paper.
Journal ArticleDOI
Rapidly Solidified Powder Metallurgy Mg97Zn1Y2Alloys with Excellent Tensile Yield Strength above 600 MPa
TL;DR: In this paper, the RS P/M alloys exhibited excellent elevated-temperature yield strength that was 510 MPa at 423 K. The specific tensile yield strength was four times as high as that of a commercial AZ91-T6 alloy, and was higher than those of conventional titanium (Ti-6Al-4V) and aluminum (7075-T 6) alloys.

Review on superior strength and enhanced ductility of metallic nanomaterials
TL;DR: In this article, the authors present an overview of experimental data and theoretical concepts addressing the unique combination of superior strength and enhanced ductility of metallic nanomaterials, and consider the basic approaches and methods for simultaneously optimizing their strength and ductility, employing principal deformation mechanisms, crystallographic texture, chemical composition as well as second-phase nano-precipitates, carbon nanotubes and graphene.

Microstructure and Elevated Temperature Properties of a Refractory TaNbHfZrTi Alloy
Oleg N. Senkov,J. M. Scott,S. V. Senkova,F. Meisenkothen,Daniel B. Miracle,Christopher Woodward +5 more
TL;DR: In this article, the properties of a refractory multi-component alloy, Ta20Nb20Hf20Zr20Ti20, were determined in the temperature range of 296-1473 K and strain rate range of 10−1-10−5 s−1.

Effect of Strain Rate Upon Plastic Flow of Steel
Clarence Zener,J. H. Hollomon +1 more
TL;DR: In this paper, an experiment was designed to check the equivalence of the effects of changes in strain rate and in temperature on the stress-strain relation in metal deformation.
Journal ArticleDOI
A Model for Boundary Diffusion Controlled Creep in Polycrystalline Materials
TL;DR: In this article, the authors discussed the mechanism of creep in polycrystalline alumina based on the differences between the lattice and boundary diffusion models and showed that the boundary diffusion model is more stable than lattice diffusion model, while the grain size dependence and the numerical constant are greater.
Journal ArticleDOI
Diffusion-accommodated flow and superplasticity
M.F. Ashby,R. A. Verrall +1 more
TL;DR: In this article, a new mechanism for superplastic deformation is described and modelled, which differs fundamentally from Nabarro-Herring and Coble creep in a topological sense: grains switch their neighbors and do not elongate significantly.
Journal ArticleDOI
Grain-boundary sliding and its accommodation during creep and superplasticity
TL;DR: In this paper, the roles of grain-boundary sliding (GBS) and of other creep mechanisms in creep and fine-grain superplasticity are presented in relation to a model based on the division of grains into their central cores and peripheral “mantles.

Superplasticity of yttria-stabilized tetragonal ZrO2 polycrystals
TL;DR: In this article, the uniaxial tensile deformation behavior of 3 molpercent Y/sub 2/O/sub 3/-tetragonal ZrO/Sub 2/ polycrystals was studied at temperatures up to 1500 C in ambient atmosphere.
