Laser micro spot welding offers temperature resistant high strength contacts without filler material. However, due to varying surface absorption properties of copper, the welding quality shows poor reproducibility. To ...

Sheet-bulk metal forming is a new production process capable of performing deep-drawing and massive forming steps in a single operation. However, due to the high forming forces of the forming process, continuous process ...

Magnesium sheet alloys have a great potential as a construction material in the aerospace and automotive industry. However, the current state of research regarding temperature dependent material parameters for the description ...

To enable in-process inspection of industrial manufacturing processes, measuring devices need to fulfill time and space constraints, while also being robust to environmental conditions, such as high temperatures and ...

NiTi shape memory alloys are considered to be difficult to machine. Dimensional accuracy can hardly be met especially in micro-machining. Being a non-contact tool and therefore independent from machining forces, the laser ...

Aluminum alloys of the 7000 series possess high lightweight potential due to their high specific tensile strength combined with a good ultimate elongation. For this reason, hot-formed boron-manganese-steel parts can be ...

The evolution of damage in geared components manufactured from steel sheets was investigated, to analyse the influence of damage caused by the sheet-bulk-metal forming. Due to the inhomogeneous and multi-axial deformation ...

Manufacturing processes as well as products have to be improved continually to meet all the requirements of international competition. Along with economic demands, changing consumer and environmental legislation lead to ...

This work focuses on the modeling of the evolution of anisotropy induced by the development of the dislocation microstructure. A model formulated at the engineering scale in the context of classical metal plasticity and a ...

Within this work uniaxial tensile tests have been performed with high-manganese TWIP-steel and different dual-phase steels to determine mechanical properties. The transfer of the results form uniaxial tensile tests to ...
