Thermodynamics and kinetics of phase transformation in rare earth–magnesium alloys: A critical review
TL;DR: In this paper, the theory and recent advances on Mg-rare earth (RE) alloys, especially for the interface stability, thermodynamics and kinetics of nucleation and growth of the key phases and matrix phases, together with their relationships with micro-structures, and macroscopic properties, are reviewed.
Journal ArticleDOI
The synergy effect of fine and coarse grains on enhanced ductility of bimodal-structured Mg alloys
TL;DR: In this article, a novel Mg-8Al-2Sn-1Zn alloy with a bimodal structure prepared by hard-pate-rolling (HPR) exhibits both higher tensile strength and ductility than its fine-grained counterparts prepared by conventional rolling.

Gravimetric, Electrochemical, Surface Morphology, DFT, and Monte Carlo Simulation Studies on Three N-Substituted 2-Aminopyridine Derivatives as Corrosion Inhibitors of Mild Steel in Acidic Medium
TL;DR: In this paper, three N-substituted 2-aminopyridine derivatives, namely, 6-(2,4-dihydroxyphenyl)-4-phenyl-2-(phenylamino)nicotinonitrile (DPPN), DPPN, DHPN, and DMPN, were investigated for their inhibitive effects on mild steel corrosion in 1 M HCl solution using electrochemical, surface, chemical, and theoretical studies.

Principles of equal-channel angular pressing as a processing tool for grain refinement
TL;DR: In this article, a review examines recent developments related to the use of ECAP for grain refinement including modifying conventional ECAP to increase the process efficiency and techniques for up-scaling the procedure and for the processing of hard-to-deform materials.
Journal ArticleDOI
Ultrahigh strength and high electrical conductivity in copper
TL;DR: Pure copper samples with a high density of nanoscale growth twins are synthesized and show a tensile strength about 10 times higher than that of conventional coarse-grained copper, while retaining an electrical conductivity comparable to that of pure copper.
Journal ArticleDOI
High tensile ductility in a nanostructured metal.
TL;DR: A thermomechanical treatment of Cu is described that results in a bimodal grain size distribution, with micrometre-sized grains embedded inside a matrix of nanocrystalline and ultrafine (<300 nm) grains, which impart high strength, as expected from an extrapolation of the Hall–Petch relationship.
Journal ArticleDOI
Revealing the Maximum Strength in Nanotwinned Copper
TL;DR: The maximum strength of nanotwinned copper samples with different twin thicknesses is investigated, finding that the strength increases with decreasing twin thickness, reaching a maximum at 15 nanometers, followed by a softening at smaller values that is accompanied by enhanced strain hardening and tensile ductility.
