Effect of Rare-Earth Additions on the Texture of Wrought Magnesium Alloys: The Role of Grain Boundary Segregation
TL;DR: In this article, two classical models (Langmuir-McClean and Cahn-Lucke-Stuwe) are used to explore the likely effect of rare-earth (RE) additions on grain boundary solute concentration and drag.

The crystallography and core structure of twinning dislocations in H.C.P. metals
Anna Serra,David Bacon,R.C. Pond +2 more
TL;DR: In this paper, the authors investigated the structural properties of hexagonal-close-packed metals using computer simulation techniques and found that the core structures, in particular the core widths, are very sensitive to the interatomic potential used and can be extremely wide for the (1012) and (1121) boundaries.

Crystallization of Al23Te77 glasses
TL;DR: In this paper, a model for non-isothermic crystallization of Al23Te77 glasses was developed on the basis of the Avrami theory, which is in agreement with isothermic results.

The interaction of CO and Pt(100). II. Energetic and kinetic parameters
TL;DR: In this paper, the authors investigated the mechanism and driving force of the CO-induced phase transition of the Pt(100) surface, and quantitatively described the energetics of this system.
