SUUUpoRt course - Material Behaviour in Deformation Processes

Students understand the complex relationships between the material and process-related influences on the forming behaviour. Furthermore students are enabled to understand and evaluate the behaviour of relevant metallic materials in industrial manufacturing processes of forming technology. The forming behaviour of different metallic materials (e.g. iron/steel, magnesium, titanium, aluminium, nickel, shape memory alloys, etc.) is estimated on the basis of information on the chemical composition, manufacturing route and material condition.

On the basis of the various semi-finished product production routes, the forming capacity of the individual materials is assessed with the aid of the metal physical properties relevant to forming. The extraction, further processing and application examples are discussed in an overview.

Contents: The main parameters influencing the forming behaviour of metallic materials are presented. State diagrams of binary and ternary alloys are presented for iron and common non-ferrous metals individually or in combination of alloying and accompanying elements. The information to be derived from them about the phase composition at different temperatures is explained and related to the forming behaviour depending on the forming conditions. Examples of flow curves and the forming capacity for selected materials and their different states underpin these relationships. Finally, the knowledge is brought into connection with cold and hot forming processes and the resulting requirements regarding the forming behaviour of the input materials or materials used. In seminars and practical courses, the knowledge is deepened and basic skills for determining material parameters relevant to forming are also taught.
