DRX: The Dynamic Deformation Regime L. E. Murr* Department of Metallurgical & Materials Engineering The University of Texas at El Paso * Shenyang National Laboratory for Materials Science, Institute of Metal Research, Chinese Academy of Sciences – Visiting Professor and Lee Hsun Lecturer in Materials Science - 2010
Acknowledgments Supported in part by the U.S. Army Research Laboratory, Aberdeen Proving Ground, MD – Prime Contract No. DATM05 -02-C-0046/Task Order #16 Supported in part by U.S. Army TACOM – Picatinny Arsenal, NJ – Prime Contract No. W15QKN-04M-0267 /Project No. 1A4CFJERIANG. Supported in part by a Mr. & Mrs. MacIntosh Murchison Endowed Chair at the University of Texas at El Paso
CONCLUSIONS Extreme Deformation –True strains above ~ 3 –Strain rate above ~ 10 3 occurs by DRX, which allows for material flow in the solid state The DRX regime is outside the “normal” deformation regime. Dynamic deformation, beyond the “normal” deformation regime, is characterized by DRX. All ASBs are a manifestation of the DRX regime.
