Nanoscale inhomogeneities are typical for numerous metallic alloys and crucially important for their practical applications. At the same time, stabilization mechanisms of such a state are poorly understood. We present a general overview of the problem, together with a more detailed discussion of the prototype example, namely, Guinier-Preston zones in Al-based alloys. It is shown that coherent s...

usd7 is one of the steel products of isfahan steel company. it is cast in continuous casting moulds and rolled up to a rod of 5 mm diameter. finally, it is wire drawn up to 3 mm and used as welding electrodes. this steel contains 0.05 to 0.09 wt. % carbon. the acceptable limit of the aluminium in this class of steel is less than 0.003 wt%. therefore, it is categorized as rimmed steel. during fo...

in this paper, we use the concept of graph convergence of h(.,.)-co-accretive mapping introduced by [r. ahmad, m. akram, m. dilshad, graph convergence for the h(.,.)-co-accretive mapping with an application, bull. malays. math. sci. soc., doi: 10.1007/s40840-014-0103-z, 2014$] and define an over-relaxed proximal point method to obtain the solution of a generalized variational inclusion problem ...

The study of the strength of correlations in NaxCoO2 is extended to the x=0 end of the phase diagram, where Mott insulating behavior has been widely anticipated. The inclusion of correlation as modeled by the LDA +U approach leads to a Mott transition in the ag subband if U Uc=2.5 eV. Thus, U smaller than Uc is required to model the metallic, nonmagnetic CoO2 compound reported by Tarascon and c...

Inclusion analysis is the name given by Operis to a black box testing technique that it has found to make the checking of key financial ratios calculated by spreadsheet models quicker, easier and more likely to find omission errors than code inspection. 1 CALCULATE MORE THAN ONCE One approach among many [Pryor, 2004] [Panko, 2006] for improving the chance that a spreadsheet delivers the results...

Purpose This study aims to examine whether social inclusion policies promote financial inclusion. Three were analyzed: gender equality policies, environmental sustainability and protection (SP) policies. Design/methodology/approach The used the panel fixed effect regression methodology analyze data from 48 low- medium-income countries. Findings results show that do not have a significant on Als...

Metallic glasses are known for their outstanding mechanical strength. However, the microscopic mechanism of failure in metallic glasses is not well-understood. In this article we discuss elastic, anelastic and plastic behaviors of metallic glasses from the atomistic point of view, based upon recent results by simulations and experiments. Strong structural disorder affects all properties of meta...
