Pressure assisted heat treatment of single crystal superalloys. (B04)

• Subject Area: Metallurgical, Thermal and Thermomechanical Treatment of Materials
• Term: from 2012 to 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 190389738

The project performs research on the pressure assisted heat treatment of superalloys and the influence of pressure, temperature and time on microstructural evolution. Heat treatment strategies for new alloys and materials produced with different methods (casting and additive manufacturing) will be developed. The rejuvenation of the initial microstructure after creep degradation by HIP-treatments represents the main research focus. HIP-experiments will also be performed with the objective to repair surface damage.
