The annealing behavior of shock-modified rutile 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 1000C. The dislocations generated by the shock treatment were found to persist essentially unaltered through the 475C anneal. Substantial recovery was observed after the 1000C anneal.
