A 304 SS flyer plate 0.54 cm thick was driven at 25 GPa at 2 ..mu..sec pulse duration. A figure illustrates the increase in hardness through the plate thickness. The higher hardness occurs at the bottom of the flyer plate. Stain-induced ..cap alpha..'-martensite morphology was obtained in the 304 specimen, just below the flyer plate from the same impact. The flyer plate microstructures from top to bottom show an increase in ..cap alpha..'-martensite as well as a significant increase in the residual dislocation densities. The ..cap alpha..'-martensite within the flyer plate for the most part is strain-induced and is observed to coalesce into laths along the <110>, in addition to being observed in a blocky structure.
