Abstract
Mathematical and natural modelling is performed for direct axisymmetric ext rusion of bars from uncompacted metal billets. In the course of mathematica l modelling optimum production parameters are determined for extrusion prov iding extruded bars with minimum porosity, and a procedure is established f or predicting the residual porosity of articles. Comparison of the results obtained points to the possibility of practical application of the mathemat ical models.
