      abstract     = {We studied the effect of friction stir processing (FSP) on
                      the microstructure and properties of high-speed twin-roll
                      cast strips made of an experimental Al–Mn–Cu–Be alloy.
                      The samples were examined using light, scanning, and
                      transmission electron microscopy, microchemical analysis,
                      X-ray diffraction, and indentation testing. During FSP, the
                      rotational speed varied, while other parameters remained
                      constant. The uniformity of the microstructure increased
                      with the growing rotational speed. In the stir zone, several
                      processes took place, and the most important were:
                      recrystallisation of the matrix grains, fragmentation of the
                      primary intermetallic particles Al15Mn3Be2 and their more
                      uniform distribution in the stir zone, fracture, and
                      dispersion of the eutectic icosahedral quasicrystalline
                      phase (IQC), transformation of tiny Al15Mn3Be2 and IQC
                      particles into the τ1-Al26Mn6Cu4 phase and precipitation of
                      Al–Mn–Cu precipitates. In the thermomechanically
                      affected zone, new dislocations formed as well as dispersion
                      of the IQC eutectic phase and recrystallisation of the
                      matrix grains. In the heat-affected zone, dissolution of
                      θ’-Al2Cu precipitates occurred. The hardness variation
                      was not severe between the stir and heat-affected zones},
