Abstract
In the work, the microstructure and selected properties of aluminium and its alloys (AlCu4Zr0.5, AlMg5, AlZn6Mg2.5CuZr) deformed with high strain rate were investigated. The cylindrical samples were compressed by a falling - weight-type impact-testing machine at the strain rate ranging from 1.77-6.06x10(2) s(-1) in order to attain true strains between phi = 0 - 0.62. After compression, the microhardness of the samples was tested and the microstructure was examined by means of both optical (LM) and transmission electron microscopy (TEM). Additionally the misorientation of selected microstructural elements using proprietary KILIN software was determined. The large density of shear bands, bands and microbands was the characteristic feature of the microstructure. The statistical width of the microbands observed in the microstructure was calculated using the mean chord method. The obtained data demonstrate reduction of the microbands width with the increase of deformation. The main object of investigations concerns the microstructure elements refinement affected by dynamic compression.
