Design of the laser dieless drawing process of tubes from magnesium alloy using FEM model

Based on the model results a set of selected design parameters from the processing window were used for a practical production of tubes from AZ31 alloy with a preset external diameter. Analyses of microstructure of initial tubes and tubes after the laser dieless drawing show that the process allows to obtain tubes with homogeneous distribution of grains and to improve initial inhomogeneity of the microstructure.
