Popis:	The kinetics of deformation processes on the yield plateau is studied in aluminum alloy 1550. It is found out that in the general case, the Luders band fronts move discretely and only in the phase of specimen unloading. A continuous motion of the deformation fronts is possible if the relaxation rate of the applied stresses due to the test machine is higher than or equal to the rate of their decrease controlled by the internal processes at a lower scale level. The discrete motion of the Luders fronts in the 1550 alloy suggests that they are not purely switching autowaves.
