This paper presents the results of studies on the influence of oxygen partial pressure (vacuum level in the chamber) on the properties of FeAl intermetallics. One of the problems in the application of classical methods of prepared Fe-Al intermetallic is the occurrence of oxides. Applying a vacuum during sintering should reduce this effect. In order to analyze the effect of oxygen partial pressu...

Various cryptosystems use exhaustive techniques to search the key space. Such search techniques should be guided in order to be computationally adequate. Here, a Genetic Algorithm, GA, is proposed for the cryptanalysis of DES-like systems to find out the underlying key. The genetic algorithm approach is adopted, for obtaining the exact key by forming an initial population of keys that belong to...

We report a stable, tunable and non-volatile converse magnetoelectric effect (ME) in a new type of FeAl/PIN-PMN-PT heterostructure at room temperature, with a giant electrical modulation of magnetization for which the maximum relative magnetization change (ΔM/M) is up to 66%. The 109° ferroelastic domain switching in the PIN-PMN-PT and coupling with the ferromagnetic (FM) film via uniaxial anis...

Abstract With the rapid development of science and technology, requirements for material performance in fields such as defense military industry are getting higher higher, it is becoming more difficult to meet multiple with a single at same time. Inspired by special structure shells, Metal-Intermetallic-Laminated composites (MIL) composite, low-cost, multifunctional properties have been prepare...

Upon the isothermal oxidation of an ODS FeAl Grade 3 intermetallic alloy, a structured oxide scale is developed between 800 and 950o C. TEM studies have revealed a three-layered structure with a top nanoequiaxed alumina, a central alumina and a bottom Fe-Al spinel. At these temperatures, aluminium outward diffusion does not seem to be suppressed neither by the spinel sub-layer nor by the yttria...
