On the nature of Guinier-Preston zones in meteoritic and lunar orthopyroxene
Introduction: Upon cooling in their host rocks, orthopyroxenes undergo cation ordering and exsolution processes. The state of order achieved during cooling [1] and the type and morphology of the exsolution products depend on the rate of cooling. Often, the formation of stable exsolution phases is preceded by the formation of metastable phases, e.g. Guinier-Preston (GP) zones. GP zones consist o...
متن کاملCharacterization of Guinier-Preston Zones by High-Angle Annular Detector Dark-Field Scanning Transmission Electron Microscopy
Age-hardened alloys are everywhere: in aeroplanes, aluminum sashes, electrical connections for computer devices, and so on. The materials that have made possible the very existence of these human inventions are manufactured based on a single materials-science principle known as ageing. Here, supersaturated impurity atoms that dissolved in an otherwise pure metal gather around inside the metal a...
متن کاملVacancy-interstitial pairs in ordered smectic phases : a linear Guinier-Preston zone behaviour
An original diffuse X-ray scattering pattern is observed for single domains of threedimensionally ordered Smectic B and G phases : a fairly sharp white line going through the center of the reciprocal space is associated with a periodic set of parallel and equidistant black lines of similar shape. It is demonstrated that this set of lines is the signature of a linear defect consisting in a local...
متن کاملMany-body interactions in the Al–Cu system
The article contains computational data of many-body interactions in Al-Cu alloys, obtained using PAW-VASP calculations. Pairwise, three-site, and four-site interactions are presented. Mentioned data are relevant to the research article "Many-body mechanism of Guinier-Preston zones stabilization in Al-Cu alloys" (Gorbatov et al., 2017) [1].
متن کاملReply to Oppenheimer and Preston
I am honored to have my essay discussed at such length by two of the most eminent scholars in the field. Because of space constraints, I will not attempt to respond to all of their points, but instead will focus on the most serious criticisms. Many of the issues raised by Preston and Oppenheimer are quite technical, and I will address them in due course. Let me begin, though, by addressing a mo...
