Creep properties beyond 1100 °C and microstructure of Co-Re-Cr alloys

▶ Co-Re-Cr alloys withstand high operating temperatures. ▶ Co-Re-Cr alloys show significantly higher LM-Parameters than X-40. ▶ Creep failure due to weak grain boundaries. ▶ Tiny precipitates of type TaC in the matrix. ▶ TaC act as obstacles for dislocations.
