Popis: Structure, texture, and mechanical properties of 150 μm thick beryllium foils obtained by multipass hot cross rolling at 870 °C in a metal container have been studied in this work. Depending on the strain ratio in the rolling and in the transverse direction, the initial fiber texture 〈10–10〉 transformed into a split basal {0001} 〈10–10〉 or into a fiber 〈0001〉 texture, which affected significantly the mechanical properties of beryllium foils. The rolled foils with a split basal texture exhibited a strong anisotropy of their mechanical properties, low strength and ductility in the transverse direction. The foils with a fiber texture demonstrated enhanced isotropic mechanical properties caused by activation of a prismatic slip in beryllium.
