Weight reduction is an important subject for the automotive and aviation industry to improve the products energy efficiency and to reduce the CO2 emission significantly. And it also helps to increase transportation range and payload. However, effective weight reduction requires advanced light-weight designs, which are indicated by the smallest portion of the right material at the right place. This often necessitates additional materials and processing costs.
Thus, in order to find an optimum relation of weight savings and costs a multidisciplinary approach is necessary that combines designing and dimensioning with materials science and production technology. Generally, the potential of materials for weight savings can be evaluated by regarding their density specific properties. While e.g. carbon fibre reinforced polymers exhibit highest specific strength and stiffness values light alloys, such as aluminium, titanium and magnesium alloys, provide an excellent impact toughness, a good wear and thermal resistance as well as a high life cycle fatigue along with significantly lower materials and processing costs and, furthermore, an out- standing recyclability. Within this material class aluminium and magnesium alloys are characterised by a high specific bending stiffness and good compression stability. Titanium alloys are more expensive, but advantageous e.g. when a very high specific tensile strength is required.
Generally, the properties are strongly influenced by the manufacturing process. This applies to both the materials processing characteristics and its performance characteristics. Starting with a digression on metallurgical fundamentals the seminar is focused on the processing, properties of aluminium, titanium and magnesium alloys and their fields of applications in consideration of essential technological aspects (i.e. basic alloy classes, general processing routes, associated and secondary processes). The seminar is geared to engineers and technicians in industrie who are working in the areas of material processing,design and application.
