Temperature and Deformation Microstructure During Shock Compression

摘要

Solids subjected to high velocity impact or explosive loading may undergo solid state or metallurgical transformation, or melting within time periods appreciably less than 10 exp -8 s, due to the intense shock-pressure environment. Nonequilibrium features unique to the shock-wave environment have been identified in the shock transformation process. These features include heterogeneous shear deformation and temperature effects which appear to control the transformation kinetics and microstructure of the transformed material. Transformation under shock loading leads to unusual microstructure in recovered material and can result in interesting and useful changes in physical and mechanical properties.
