Rolling is one of the most employed industrial processes which can be used at multiple manufacturing stages, allowing different geometries such as plates, rods, profiles, billets, slabs, tubes, and seamless tubes to obtained. However, rolled products develop anisotropy due preferential orientation crystals in rolling direction. Thus, some process configurations processing parameters (e.g., thic...

Abstract. The technological process of manufacturing cold-rolled strip with a thickness 0.5-1.5 mm from high-strength steel grades on cold rolling mills can consist 2 or even 3 operating cycles "cold - intermediate annealing". This is due to significant hardening such steels during and, as result, limitations the maximum allowable forces. Each additional cycle annealing" significantly increases...

cold rolling process of a major transformation in the form of sheet metal and a wide range of steel products are produced in this way. elastic deformation during cold rolling working rollers and the inevitable increase in the rolling force. in this study, the effect of elastic deformation during cold rolling mill rollers working on the reciprocating back and forth in tandem with the presence of...

The superconducting high-entropy alloys (HEAs) recently attract considerable attention due to their exciting properties, such as the robustness of superconductivity against atomic disorder and extremely high pressure. well-studied crystal structure HEAs is body-centered cubic (bcc) containing Nb, Ti, Zr atoms. same elements are contained in $$\mathrm {Al}_{5}\mathrm {Nb}_{24}\mathrm {Ti}_{40}\m...

When a cross-domain robot (CDR) flies on the water surface, large pitch angle and roll may lead to flooding into cabin or even overturning. In addition, CDR is influenced by some uncertain parameters external disturbances, such as resistance current. To constrain attitude improve robustness of controller, non-singular terminal sliding mode asymmetric barrier control (NTSMABC) algorithm proposed...

The resistance against rolling of a rigid cylinder on a flat viscous surface is investigated. We found that the rolling-friction coefficient reveals strongly non-linear dependence on the cylinder’s velocity. For low velocity the rolling-friction coefficient rises with velocity due to increasing deformation rate of the surface. For larger velocity, however, it decreases with velocity according t...

We propose a new variant of the Affleck-Dine baryogenesis mechanism in which a rolling scalar field couples directly to leftand right-handed neutrinos, generating a Dirac mass term through neutrino Yukawa interactions. In this setup, there are no explicitly CP violating couplings in the Lagrangian. The rolling scalar field is also taken to be uncharged under the B − L quantum numbers. During th...
