Registration of Free Surface Velocity Dispersion of Iron and Steel Samples by Optical Lever Method

Abstract

Results of explosive experiments are presented with time-resolved and space-resolved diagnostics of free surface velocity profiles of wedge samples by optical lever method. The objective of this work is to record free-surface velocity dispersion of samples made of high purity iron with fine and coarse grains, as well as 30KhGSA steel, in delivery state and hardening up to HR c 50. It is demonstrated, that the value of velocity dispersion of free surface of the samples under identical loading modes is varied according to initial microstructure and grain size of investigated metals.
