The location, size and reflection characteristics of bond-line voids of a titanium alloy superplastically formed and diffusion bonded (SPF/DB) test specimen were detected by a high resolution 50MHz ultrasonic C-scan system. These voids were undetectable using conventional ultrasonic inspections. Pre ...
kij and ϑij are the coefficients of thermal conductivity and the moisture diffusion, respectively. nj represents the unit outward normal to natural boundaries. View article Journal 2021, Thin-Walled StructuresLiming Zhou, ... Krzysztof Kamil Żur Chapter Applications of Numerical Modeling in ...
However, in the case of the long-term high-resolution experiment, it is difficult to increase the vertical resolution and conduct many sensitivity experiments with the subgrid diffusion parameters altered, because the calculation time becomes extremely long. Thus, short-term three-dimensional regional ...
Herein, we developed a new type of ENRR catalyst by immobilizing Bi2O3nanoplates onto the surface of FEG, to form the free-standing hybrid material (Bi2O3/FEG), which was then directly used as an electrode for ENRR in different electrolytes under ambient conditions. In this ENRR system,...
An operator of the magnetic resonance imaging apparatus appropriately sets various scanning parameters prior to a scan, and obtains information required for an examination, such as contrast, Signal to Noise ratio (SN ratio), spatial resolution, flow velocity, and diffusion. The scanning parameters inc...
Based on current theories of diffusion and creep cavity closure at high temperatures, atheoretical analysis of diffusion bonding under super-plastic condition for Ti-6Al-4Vtitanium alloy is carried out. The diffusion bonding is mainly described as a two-stageprocess:1 The shrinkage process of ...
In their model, Guo and Liang [116] used Fick’s Law to model chloride diffusion and Semi-Markov chains to model the probabilistic transitions between various deterioration states. Moreover, Furtado and Ribeiro [117] used semi-Markovian models to evaluate the effect of various deterioration ...
The diffusion of both H2O and SO2 through the zeolite framework can potentially be attributed to two concomitant factors: increased hydration of 13X at 45RH% or higher sulfur uptake during the FGD process. To gain further insight into the two systems, thermogravimetric (TG) and microchemical EDS...
