For working out the approach of acquiring low planar anisotropy while achieving high ridging resistance and r-value, during two step cold rolling processes with different total reductions texture evolution corresponding mechanism were investigated for ferritic stainless steel. During rolling, crystallites having orientations near {1 1 1} 〈1 2〉 Goss induced by shear bands further deformation orientation tended to rotate towards more stable 2〉. subsequent annealing, these recrystallized nuclei...
Abstract Tropical cyclone (TC) intensity is strongly influenced by surface fluxes of momentum and moist enthalpy (typically parameterized in terms “exchange coefficients” Cd Ck, respectively). The behavior Ck remains quite uncertain especially high wind conditions over the ocean; moreover, flux extremely sensitive to sea temperature (SST). This study focuses on numerical simulations Hurricane Katrina (2005) from an atmosphere–ocean coupled modeling system examine combined impacts air–sea...
Digital twin is one of the newly-emerged enabling technologies for achieving intelligent manufacturing. Based on physical–digital convergence, digital provides manufacturing systems with a new model collaboration between workforce and industrial processes. With characteristics real-time communication data-driven enablers, scheduling strategy requires close cooperation workers, However, in process digitization intelligentization, industry will need to face challenge supporting worker skills...
Abstract The application of the wave boundary layer model (WBLM) for wind stress evaluation to storm modeling is studied using Hurricane Katrina (2005) as an example, which chosen due its great intensity and good availability field data. WBLM based on momentum energy conservation equations takes into account physical details air‐sea interaction processes well dissipation presence sea spray. Four widely‐used bulk‐type formulas are also used comparison. Simulated significant heights with shown...
One of the most difficult challenges for modern manufacturing is reducing carbon emissions. This paper focuses on green scheduling problem in a flexible job shop system, taking into account energy consumption and worker learning effects. With objective simultaneously minimizing makespan total emissions, (GFJSP) formulated as mixed integer linear multiobjective optimization model. Then, improved sparrow search algorithm (IMOSSA) developed to find optimal solution. Finally, we conduct...
The effects of Ba content on the dynamics crystallization process, which ultimately determines grain size, were studied in barium ferrite thin films. Rapid thermal annealing was used to crystallize amorphous as-deposited time and temperature dependent crystalline volumes determined from magnetization films, analyzed by means Johnson–Mehl–Avrami relation. Microstructural studies showed that films with higher had nucleation rates lower growth rates; consequently, they finer size smaller aspect...

OW can be obtained both high ratios. Better than -14 dB NLTS was measured at...
Spin-dependent tunneling (SDT) materials with bottom-pinned structure (substrate/Ta/NiFeCr/PtMn/CoFe/t Al2O3/CoFe/NiFe/Ta) are fabricated by magnetron sputtering in ultrahigh vacuum. In this study, a two-step natural oxidation was used, which the second Al layer deposited and naturally oxidized after of first layer. The top bottom leads were also patterned into bow-tie shaped structures. process results perfectly decoupled pinned free film total as-deposited aluminum thickness 7 Å, whereas,...
