Aluminum alloys show a low weight, relatively high specific strength, good corrosion resistance in neutral environments and high electric and thermal conductivity. It makes them of interest for production of various functional components in aerospace and automotive industry. Wrought alloys generally have good formability and they are processed by common technologies, such as extrusion, forging,...

The evolution of crystallographic texture during the thermo-mechanical processing aluminium sheet is accompanied by development plastic anisotropy and, most notably, well-known earing phenomenon. In present paper we analyse formation and properties in sheets Al-Mg alloy AA 5050A (ISO AlMg1.5(D)) along a process route resulting temper H16 after cold rolling H44 lacquering. This route, which char...

In this paper, glass fiber-reinforced polypropylene (GF50-PP) composite composed of long fibers was prepared by the thermo-compression process for very first time. This presents high mechanical strength and is used in infrastructures, which demand resistance against severe conditions. Mechanical multi-scale damage analysis GF50-PP at ambient cryogenic temperatures have been investigated study u...

The starting material used in this study was a cake generated during thermo-mechanical fractionation of sunflower (Helianthus annuus L.) whole plant in a twin-screw extruder. It was slightly deoiled (16.7% of oil in dry matter). Composed mainly of fibers and proteins, it could be considered as a natural composite and was processed successfully into fiberboards by thermo-pressing. This study aim...

Effects of the polymer infiltration processing (PIP) temperature between 850 and 1050 °C on mechanical thermal properties Nextel 312 fibre SiCO ceramic matrix composite were studied. The aim was to optimise material system for its proposed application as a gas-seal at temperatures up 900 °C. microstructure failure behaviour room characterised using electron microscopy (SEM, TEM), X-ray diffract...

In this paper, the general case of an anisotropic thermo-electro elastic body subjected to static biasing fields is considered. The biasing fields may be introduced by heat flux, body forces, external surface tractions, and electric fields. By introducing proper thermodynamic functions and employing variational principle for a thermo-electro elastic body, the nonlinear constitutive relations an...

High temperature plastic flow properties of two phase TiAl alloys containing 45 to 49 at.%Al have been investigated in thermo-mechanically grain refined materials in order to clarify the favourable microstructure and chemical composition for TiAl based superplastic materials. Grain sizes of thermomechanical treated materials and their grain size stability during subsequent high temperature defo...
