Criteria are selected for the selection of conditions allowing one, after extrusion, to obtain a bar suitable for subsequent thermomechanical processing. The obtained data is supposed to be used for technological calculations of the processes for the production of engineering parts by powder metallurgy methods. © 2023 The Authors.

Introduction Parts for general engineering purposes occupy a predominant place in powder metallurgy. So, in recent years, up to 80% or more of the powder parts market in Europe was accounted for by engineering products based on iron Gundermann (2015), Wimbert (2014), “ F ig 1”. The indicators are similar in the countries that are leading producers of powders and products from them in North America (USA, Canada) and in Asia (China, Japan, South Korea, India). One of the main consumers of iron powders and steels, as well as products from them, is the automotive industry of developed countries in Europe, America and Asia (automotive parts, including engine parts, transmissions, valves, 16th International Conference on Mechanics, Resource and Diagnostics of Materials and Structures (MRDMS 2022) Calculating the parameters of extrusion of bars from iron-based powder compositions Andrey Polyakov, Pavel Polyakov* Institute of Engineering Science, Ural Branch of the Russian Academy of Sciences, Ekaterinburg, Russia Abstract An algorithm is proposed for calculating the technological parameters of the process of extruding rods from iron-based powder compositions, which makes it possible to predict the density of the rods depending on the initial porosity of the briquette, the drawing ratio, the taper angle of the matrix, and determining the extrusion pressure.
