A study of the development of deformation and transient and residual stresses during quenching in aluminum alloy W319 is presented. Rapid tension tests were performed on W319 in the supersaturated solution state at several temperatures and strain rates. A material model following the mechanical threshold stress (MTS)–Voce formulation is developed and implemented in both a simple one-dimensional...
The excited state isomerization of thioflavin T (ThT) is responsible for the quenching of its fluorescence in a nonrestricted environment. The fluorescence quantum yield increases substantially upon binding to amyloid fibers. Simulations reveal that the variation of the twisting angle between benzothiazole and benzene groups (φ1) is responsible for the subpicosecond fluorescence quenching. The ...
In the present research, the effect of the homogenization process and annealing temperature were investigated for the 1.4470 ferritic-austenitic stainless steel in the as-cast condition. In this regard, microstructural evolutions, hardness, and impact energy of the steel was evaluated with different heat treatment conditions. The results show that the minimum volume fraction of austenite phase ...
