Shock wave effects during a Taylor test

Abstract
The Taylor test was performed in the classic way. A
cylindrical specimen was accelerated to a rigid target consisting of WC. The
specimen was of a low carbon steel, German grade Ck15, and the geometry was
5 mm in diameter and 32.5 mm in length, respectively. The test velocity was
208.5 m/s and was measured by a single laser barrier. A metallographic
investigation revealed that the specimen showed at the target a region with
non-deformed grains, whilst the hardness was increased compared to the
non-deformed end of the Taylor specimen. This zone is surrounded by a highly
plastically deformed microstructure. This microstructure and the increase in
hardness can only be explained by the appearance of a shock wave.
