In 1966, Bergmann and Barrington1 reported that, for a variety of oxide and carbide powders, improvement in the sintering behavior was obtained when the powders were subjected to explosive shock treatment. They concluded that, for the carbides, the improvement resulted primarily from the reduction in particle size, but for the oxides, the change was associated with a substantial increase in the internal defect population. Subsequent transmission electron microscopy showed high concentrations of dislocations in the shock-modified powders.2 Later work has shown that very high concentrations of point defects are generated in shock-loaded rutile powders.3
