Chemical reactions in controlled high-strain-rate shear bands
- Department of AMES, University of California, San Diego, California 92093-0411 (United States)
Controlled high-strain-rate shear bands were generated in porous mixtures (Nb+Si, Ti+Si) using axially symmetric experimental configurations ({open_quotes}Thick-Walled Cylinder{close_quotes}) method. Shear strains up to 100 and strain rates of approximately 10{sup 7}sec{sup {minus}1} were generated inside shear bands. Particle fracture, melting, and regions of partial reaction were observed inside shear bands for the Nb+Si system. Under the same conditions of deformation, for the Ti-Si system the reaction initiated inside shear bands and propagated through the entire sample. {copyright} {ital 1996 American Institute of Physics.}
