Analysis of Temperature Influence on Strain-Speed Parameters of Radial-Shear Rolling of Al-Zn-Mg-Ni-Fe Alloy

The comprehensive analysis of temperature influence on the strain-speed parameters of radial-shear rolling of Al-Zn-Mg-Ni-Fe alloy including the investigation of rheological properties, FEM simulation, and in-depth analytical interpretation of results was carried out. The rolling temperature has significant effect on the kinematic of metal forming, speed parameters, configuration, and length of trajectories. With the decrease in temperature, the speed of metal movement reduces, and this is the same for different components. The greatest decrease is noted for the axial speed component. In general, according to the nature of effect on the strain kinematic state, a temperature reduction of 100 degrees C (from 500 to 400 degrees C) acts similarly to a decrease in feed angle of about 4 degrees and, in particular, increases the rolling time, nonuniformity of deformation, tightening, and temperature effect of deformation heating.
