PLASTOMETRIC SIMULATION OF HOT ROLLING OF AL MG3 ALLOY
Original language description
Hot rolling of an alloy Al Mg3 was physically simulated by anisothermal uniaxial compression tests performed on the Hot Deformation Simulator HDS-20. The main aim of the research was to define the effect of the finish rolling temperature (in the range from 250 to 350 degrees C) on the structural and mechanical properties of the investigated alloy. The ten height passes with the uniform size of approx. 10.4 % lead to samples upsetting from the initial height of 15 mm to the nominal height of 5 mm, which corresponded to the total height deformation of 67 %. Strain rates were chosen uniformly as the 3 s(-1). Two simulations, even at the strain rate of 13 s(-1), were performed in order to make a supplementary assessment of the influence of strain rate on the properties of the investigated alloy. Metallographic analyses demonstrated an intensive forming of the structure in the central area of the samples, which resulted in a strong flattening of the individual grains. It can be assumed on the basis of the obtained results, that significant suppression of recrystallization occurred in most cases and the resultant microstructure was mainly influenced by the strengthening cumulation from partial passes without significant effect of the softening processes. Lower finish rolling temperatures clearly lead to a gradual increase of the hardness HV10 by tens of percent.
