The use of aluminum alloys for external strengthening reinforced concrete (RC) beams has been capturing research interest. Exposure to harsh environmental conditions can severely impact the efficiency. This works aims investigate degradation in mechanical properties alloy AA 5083 plates when exposed temperatures ranging from 25 300 °C. Quasi-static Isothermal tensile experiments were conducted ...

The origin of non-centrosomal microtubules was investigated in a variety of animal cells in culture by means of time-lapse digital fluorescence microscopy. A previous study (Keating et al. (1997) Proc. Nat. Acad. Sci. USA 94, 5078-5083) demonstrated a pathway for formation of non-centrosomal microtubules by release from the centrosome. Here we show a parallel pathway not dependent upon the cent...

Superplastic deformation has a significant industrial application value due to the large elongation, which allows manufacturing parts with complex geometries but happens at elevated temperatures and low strain rates. Therefore, it requires alloys fine grain size whose grains tend grow processing temperatures. Second-phase particles can promote boundary pinning keep structure during superplastic...
