ArcelorMittal Frýdek-Místek, Frýdek-Místek, Czech Republic The final Goss texture in grain-oriented electrical steels (GOES) is affected by microstructure evolution and inheritance during the whole production process. This paper presents the results of detailed...

the full annealing aa6061 aluminum alloy was subjected to severe plastic deformationvia the combination of equal channel angular pressing (ecap) and cold rolling (cr) in order torefine its microstructure and to improve its mechanical properties. according to the results of hotand cold tensile tests, the combination of ecap and cr significantly affected the final strengthand ductility of studied...

the mechanical properties and microstructural developments of 321 stainless steel during thermomechanicalprocess were investigated. the repetitive cold rolling and subsequent annealing wereconducted to achieve nanocrystalline structure in an aisi 321 stainless steel. heavily cold rolling at−20°c was conducted to form martensite in metastable austenitic steel. the process was followed byannealin...

Cold-rolled silicon steel strip products are widely used as the main soft magnetic components in cores of electrical motors, generators, and transformers. In case rotating machines, so-called non-oriented electro-technical steels normally applied. They characterized by a similar behaviour to induced field found all sheet plane directions. The kind alloys that defined herein not only possess an ...

Self-propagating exothermic formation reactions have been intensively studied in a variety of reactive multilayer foils, such as Ni/Al, Ni/Si, and Nb/Si foils. These foils contain numerous alternating nanoscale layers of elements with large negative heats of mixing. With a small thermal pulse, atoms diffuse normal to the layering and result in a rapid exothermic reaction. The heat produced is c...

A fuzzy logic controller (FLC) is designed to maintain constant tension for tandem rolling mills. Envisioning fuzzy inference system as neural network and introducing tutor, backward propagation algorithm is used as self-organization technique for FLC to approach the best parameters under supervision. Simulation results exhibit the generalization and adaptivity of neuro-fuzzy controller in offl...
