The objective of this transfer project is the transfer of single-crystal (SX-) repair from subproject B5 to crack patterns, both in the oxidized and in the non-oxidized state, in use of an identical powder material. The crack patterns are multiscaled and artificially applied to the tips of high-pressure turbine blades and to high-pressure shrouds. In addition, the mentioned SX-repairs are mechanically characterized in a hot tensile test. With these two key areas of investigation, the SX repair is expanded to include new alloys, material conditions and components from flight operations without prior dissimilar repairs.
