Most metallurgical properties, e.g., dislocation propagation, precipitate formation, can only be fully understood atomistically but most phenomena and quantities of interest cannot measured experimentally. Accurate simulation methods are essential first-principles density functional theory (DFT) is prohibitively expensive while empirical interatomic potentials rarely sufficiently accurate for a...

Oxidation behavior of metastable mechanical alloys in the Al–Mg binary system has been examined in the context of high-energy density materials and combustion applications. Mechanical alloy powders with compositions ranging from Al0.95Mg0.05 to Al0.5Mg0.5, as well as the component metals, were heated at 20 K/min in oxygen. Differential thermal analysis and thermogravimetric analysis showed that...

Article history: Received 2 August 2016 Received in revised form 14 September 2016 Accepted 15 September 2016 Available online xxxx Serrated flow, also known as the Portevin-Le Chatelier effect, has been extensively investigated in binary Mg-alloys such asMg-Ag,Mg-Y andMg-Li alloys. Interestingly, however, this effect has not been observed inMg-Al alloys. In this work, we report the appearance ...
