“…Reviews of recent advances and trends in aluminum-cladded numerical models predominantly discuss the bonding behavior and quality of rolled structures [19]. There is more attention during research on texture evolution [20] and experimental verification of accumulative roll bonding [21] than for already cladded and further cold-rolled products.…”

The present study investigates the accumulative roll bonding process applied to the EN AW 3003 aluminum alloy, serving as a composite material on both sides and consisting of the EN AW 4343 aluminum alloy. For the characterization of the optical microscopy, corrosion tests with saltwater acetic acid and mechanical properties before and after the braze test were employed. The numerical simulations accurately predicted the industrial cold rolling values for the rolling force and surface temperature. The most comprehensive understanding of the cold rolling parameters for both side-cladded materials was achieved by combining predictions for cladded and uncladded materials. The thickness of the cladded layer presented as a percentage after roll bonding was 18.7%. During the cold rolling and annealing, the cladded thickness was increased to 24.7% of the final 0.3 mm of the total cold-rolled product thickness. According to the performed braze test for final thickness, the ultimate tensile strength and yield strength were decreased, and the elongation increased to 18.1%. In addition to the described changes in mechanical properties, the material’s anisotropy improved from 5.4% in the cold-rolled condition to 2.0% after the braze test. After multiple re-meltings of the cladded material, the analyzed chemical compositions allow for recycling and reuse as different 4xxx, 5xxx, and 6xxx alloys.

“…This predicates the use for CW of such processes as stamping, rolling, extrusion, and wire drawing. 107,113) It is our belief that HPT can add new colours to the palette of studies on CW, both fundamental and applied ones. This is suggested by recent investigations of solid state 'turbulence' (cf.…”

This overview highlights some salient features of one of the most popular severe plastic deformation techniques: high-pressure torsion (HPT). It focuses on the unresolved challenging problems of HPT. The problems selected touch upon some fundamental questions of mechanics of plasticity, fracture, and friction that are at the core of the HPT process. The scientific significance of these problems and the proposed pathways to resolving them are discussed. The article is meant to promote the use of HPT as a potent tool for studying plasticity at large strains theoretically and also as a practical method enabling novel micromanufacturing routes.

“…In order to explore the variation rule of compressor flow field parameters under the unstable operation of the engine, study the variation rule of characteristic parameters when engine surge is caused by intake distortion, and strengthen engine safety monitoring and evaluation, it is necessary to monitor and analyze the unsteady flow field and working parameters of a certain turboshaft engine. This is conducive to improving the state monitoring ability of unstable surge of a certain engine [2][3][4][5]. At the same time, the change rule of characteristic parameters is extracted, which can transform the anti-surge control of a certain type of engine from passive control to active anti-surge control based on signal characteristics, so as to provide support for the safe use of helicopter under the condition of engine installation, and provide helicopter flight safety in an all-round way, which is of great significance.…”

In order to explore the engine surge when inlet distortion index and engine surge margin, the relationship between the parameter characteristics of research engine surge, strengthen safety monitoring assessment engine, this paper designed a kind of a certain type of engine bench test surge monitoring system, and unstable flow field of a certain type of vortex axis engine working parameters for monitoring and analysis. In this paper, a plug-plate distortion generator is used to induce a surge engine, and the circumferential static pressure changes of the inlet and outlet of the engine, the axial compressor and the centrifugal compressor under different working conditions are obtained. The changes of circumferential unevenness and mean turbulence, the pressure ratio at working point and the converted air flow rate at working point are analyzed with the increase of the height of the plug-plate under different working conditions. The results show that the distortion index of the working point increases and the surge margin decreases with the increase of the height of the plug-plate at the same rotating speed. When the height of the plug-plate is similar, the higher the speed is, the greater the distortion index of the working point is, and the smaller the surge margin is.
