The elastic and mechanical behavior, from room temperature up to 1300 deg; C, of Stoichiometric polycrystalline magnesium aluminum spinel is studied. Elastic modulus, fracture toughness, and modulus of rupture measurements and observations of polished and fracture surfaces have been performed. Two well‐differentiated regions of fracture behavior as a function of temperature have been found. In the low‐temperature region, this material behaves elastically, whereas in the high‐temperature (>800 deg; C) region, plastic phenomena take place.
