Micromechanical Analyses of the Shock Processing of Ductile Materials

Puntos clave

Shock compaction demonstrates unique micromechanical responses in ductile materials during high-stress events, revealing new properties.
The impact of stress waves approaches up to 1.0 MBar, inducing localized plastic flow within particles of various diameters.
Numerical calculations are utilized to simulate particle behavior under extreme conditions, given the limitations of experimental methods.
These findings underscore the importance of thermal effects and stress propagation in the processing of ductile materials.

Resumen

Abstract Shock compaction provides a means of synthesizing and consolidating materials with novel microstructures in bulk form. Two-stage, light gas guns and explosives generate high amplitude (0.1 - 1.0 MBar) stress waves that propagate through the powders which result in high temperatures and localized plastic flow. Most of the experiments use particles that have diameters ranging from 0.1 to 100.0 μm. The rates of change of the temperature and stress are too high and too localized to determine the time histories of individual particles experimentally. Numerical calculations must therefore be used to calculate the micromechanical response of the powder particles. The accuracy of the numerical calculations is verified by comparing the calculated response to experiments.
