Production and Component Behaviour
In the framework of the research of the group "Production and Component Behaviour" the interactions between production processes, component state and component behaviour at mechanical loading are investigated. The production processes considered are available either in the laboratories of production techniques of IAM-WK or within cooperations with institutes of production sciences. They are subdivided into the main groups of production processes according to DIN as follows:
- Micro Powder Injection Moulding
- Micro Casting
- High Speed Cutting
- Micromachining, Microerosion
- Laser ablation
Altering of Materials Properties
- Altering of Materials Properties
- Case Hardening of Steels
- Laser Hardening
- Shot Peening
- Deep Rolling
- Laser Schock Peening
A main subject of the research of the section "Production and Component Behaviour" is the characterisation of production induced component or surface states using metallographic and x-ray methods, which are available from the corresponding sections of the institute. microstructure and properties structure and stress analysis.
Besides this devices of the laboratories of production techniques and the laboratories of mechanical testing are involved in the determination of the stability of surface layer states at thermal, quasistatic, cyclic and combined loadings. Additionally, in the laboratories for mechanical testing the effects of production induced component states on strength, especially fatigue strength, of metallic and ceramic materials are investigated.
An additional important main subject of the research of the section "Production and Component Behaviour" is the Simulation of the generation of productopn induced component states at different production steps. Here, different Finite-Element-Programmes Numerical Simulation are used to describe especially thermo-mechanically coupled processes, if necessary including phase transformations. The necessary input data are determined experimentally Laboratory of production technoiques.
