AB  - The aim of this work is to analyse the process of friction stir welding (FSW) of 3 mm thick aluminium plates made of high strength aluminium alloy - 2024 T3, as well as to assess the mechanical properties of the produced joints. Friction Stir Welding is a modern procedure which enables joining of similar and dissimilar materials in the solid state, by the combined action of heat and mechanical work. This paper presents an analysis of the experimental results obtained by testing the butt welded joints. Tensile strength of the produced joints is assessed, as well as the distribution of hardness, micro-and macrostructure through the joints (in the base material, nugget, heat affected zone and thermo-mechanically affected zone). Different combinations of the tool rotation speed and the welding speed are used, and the dependence of the properties of the joints on these parameters of welding technology is determined.

AB  - A mechanism of high-temperature plasticity has been studied in terms of stress exponent and activation energy for deformation. A Ti3Al-based intermetallic was processed by hot-rolling in the two-phase field to accomplish a fine-grained microstructure. Compression stress-strain tests were conducted in the temperature interval rangin from 900 to 1050 degrees C and strain rates between 6.9 . 10(-5) and 2.7 . 10(-2) s(-1). Results indicate that viscous-drag dislocation glide and grain boundary sliding are the main mechanisms of deformation. Activation energy for deformation suggests dependency on the solute content in the beta-phase.

AB  - Ti3Al-11Nb-1V (x/%) was made in a vacuum arc furnace. Hot-rolling was conducted at 1050 degrees C in a two-phase field of the alloy. Strain-rate jump tests were performed at T = 800-1100 degrees C and strain rates of 10(-6) to 10(-3) s(-1). Creep stress exponent (n) and activation energy for deformation (Q) were used to identify deformation mechanisms. Two sequential mechanisms are revealed: (i) viscous glide, typical of solid solution alloys and, (ii) power law breakdown at lower temperatures. Activation energy for deformation was found to be strongly stress-dependant.
