Archives of Civil and Mechanical Engineering

Vol. 19, no. 1

268--273

The paper presents the results of research on the rheological properties of the Zr–1%Nb alloy, obtained for the strain parameters corresponding to the cold rolling tube process in a pilger mill. The studies were carried out under conditions of continuous, discontinuous and variable load in the GLEEBLE 3800 metallurgical processes simulator, according to the program developed on the basis of conditions occurring in the actual technological process. The influence of the strain, strain rate, plastic deformation thermal effect and the Bauschinger effect on changes in the flow stress was determined. Recommendations for division of the alloy strain distribution over the length of the deformation zone in the pilger roll grooves is presented.
