Abstract

The annealing behavior of shock modified rutile (TiO2) powder was studied by transmission electron microscopy, x-ray line broadening, and electron spin resonance. Specimens were examined in the as-received and as-shocked conditions, and in shocked and annealed conditions after one hour at 475° or 1000°C. The dislocations generated by the shock treatment were found to persist essentially unaltered through the 475°C anneal. Substantial recovery was observed after the 1000°C anneal.
