Summary

The mechanical properties of two doped lanthanum chromite perovskites were evaluated with respect to strength, fracture toughness curve and elastic modulus. With decreasing oxygen partial pressure during annealing at 1000°C the room temperature mechanical properties improved significantly. Calculations show that the flaw size is not affected by the annealing.
