Acoustic-Emission Diagnostics of the Fatigue Fracture of Aluminum Alloys of the Al–Zn–Mg–Cu System

Scandium in aluminum alloys behaves as the most efficient modifier of the structure of the material and as an agent suppressing recrystallization. This unique behavior of scandium in alloys of the Al-Mg system greatly increases the strength characteristics, whilst retaining on a higher level the ductility and processing properties of deformed semi-finished products. This article describes the effect of complex alloying the Al-6.3% Mg alloy with scandium, manganese and zirconium on the weldability and strength properties of the material is of considerable scientific and practical importance.Investigations.

Generalization the experience building for the cultivation of champignons shows the diversity of construction solutions. The method of layer-by-layer assembly with galvanized steel and aluminum alloy coverings is economically feasible to use in champignons of frame structural scheme, enclosing structures of industrial premises. However, the technologically required wet air conditions of the premises and aggressive gases during construction design complicate the selection of a rational type of outer layers of enclosing structures. To reveal the rational material of coverings in the production premises of champignons, corrosion tests are carried out on samples of aluminum alloys of the Al-Mg, Al-Mn, Al-Mg-Si systems, technical aluminum, galvanized steel and galvanized steel with a protective coating. The type and corrosion penetration rate are set for the exposed samples. According to the test results, suitable covering materials for various types of champignon production premises are determined

Alloys Of The Al

Aluminum alloys of the Al-Mg system are widely used in automotive and aviation industries due to their combination of strength, good ductility and corrosion resistance. Increasing the percentage of magnesium leads to higher strength of the material with a slight reduction of ductility. Behavior of critical stresses in materials were studied under variable strain rate loading conditions. The possibility to predict critical dynamic stresses of materials based on a structural-time approach is discussed.
