that the relatively uniform microstructure with fine α-Al crystals is able to postpone the growth of pits [43]. This is in agreement with the results of the microstructure in the present work which indicates......
is considered as a diffusion-controlled process, and the increase of aging time promotes the nucleation and growth of precipitates. In order to quantitatively analyze the effects of initial δ phase......
due to the Friedel–Escaig mechanism; 3) At temperatures ranging from 573 to 723 K, both bulging of original grain boundaries and subgrain growth were the operating DRX mechanisms and controlled......
(2): 273-281. [40] CHEN X B, ZHOU X, ABBOTT T B, EASTON M A, BIRBILIS N. Double-layered manganese phosphate conversion coating on magnesium alloy AZ91D: Insights into coating formation, growth......
to the compactness of void in soft rock, while the drop is due to the fact that the increase of plastic strain causes internal particle bonds to continuously diminish and induces the micro-cracks growth......
motility at boundaries for the nucleation, growth of dynamically recrystallized grains and dislocation annihilation [19]. Figure 5 shows the EBSD microstructure of pure aluminum under different......
average values during the summer (24.23 °C), and lower average values in the winter season (7.67 °C). Water temperature influences the chemical and biological activity besides growth of aquatic......
on the science of genetics to describe the process of natural growth of organisms. GA has been successfully applied to network design problems [34]. Since each objective constraint shown by Eqs.(29)-(31) needs......
, the formation of porosity becomes unavoidable. The preferential nucleation and growth of gas bubbles during solidification lead to various kinds of porosities. Fig. 12 FESEM images of AA6061/TiC AMCs......
constituents provide the locations for the crack nucleation and growth [2,12-15]. Considerable studies have been conducted on the correlations between the intermetallics and castability and weldability......
