|
|
| Development of process layout for LMD to achieve the required characteristics with respect to material, part quality and economy | |
| First time development of process layout for DLF to achieve the required characteristics with respect to material, part quality and economy | |
| Development of heat treatment cycles before and after laser treatment to get microstructures and thermal stress fields that meet the mechanical properties | |
| Determination of static and dynamic mechanical properties of the laser-processed and heat-treated samples together with correlation of these properties with microstructure and stress fields | |
| First time workout of acceptance plus a non-destructive test (NDT) inspection criteria for LMD and DLF process (correlations between tolerable defects, microstructure, mechanical properties and process parameters) | |
| Support of the process development by simulation of temperature, stress fields and microstructure formation to predict process parameters and build-up strategies | |
| Development of equipment for LMD and DLF processes, such as processing heads, including powder feeding nozzles and shielding gas units for 3D processing, process chamber for DLF, software for CAD/CAM integration, and sensors and systems for on-line process control | |
