In this study, aluminide coating was employed to enhance the high-temperature cyclic oxidation of Rene-80 superalloy at 950ºC. The microstructural aspects and phase constituents of samples were investigated with scanning electron microscopy (SEM) and x-ray diffraction (XRD) techniques. The result of oxidation tests showed that the weight gain in the uncoated sample was considerably higher than...
The paper discusses the basic issues of local approach to ductile fracture structural metals, with particular emphasis on failure due microvoid development. mechanisms nucleation voids around inclusions and precipitates are characterized. criteria for resulting from cracking existing particles or their separation material matrix presented. Selected results experimental studies Finite Element Me...
During Non-Rapid Eye Movement sleep (NREM) the brain is relatively disconnected from the environment, while connectedness between brain areas is also decreased. Evidence indicates, that these dynamic connectivity changes are delivered by microstructural elements of sleep: short periods of environmental stimuli evaluation followed by sleep promoting procedures. The connectivity patterns of the l...
