Abstract

Fundamental studies and applied developments in the treatment of materials by explosive energy, carried out at the Institute of Hydrodynamics and the Special Design Bureau of Hydroshock Technology of Siberian Branch of the Academy of Sciences of the USSR, are reviewed. Those studies and developments have taken place in the areas of explosive strengthening, explosive welding, and explosive powder compaction. The strengthening of high-manganese steel and other materials, railroad frogs, and explosive heat treatment are discussed. The physicomechanical aspects, metallography, and applications of explosive welding are assessed, using nickel superalloys and stainless steels as specific examples. The effects of explosive shock treatments on the structure and mechanical properties of alloy and powder materials were addressed.
