Ae. Kheifets et al., PERIODIC CHARACTER OF THE PHASE-TRANSFORMATION IN STEEL ACCOMPANYING REFLECTION OF CONVERGING SHOCK-WAVES FROM THE CENTER OF FOCUSING, JETP letters, 67(10), 1998, pp. 849-855
Special conditions in an experiment on the loading of low-carbon steel
by converging shock waves made it possible to obtain residual microst
ructural changes of a periodic character, with a period of the order o
f 0.2 mm, which are associated with a phase transformation caused by w
aves reflected from the center of focusing. A model explaining the per
iodicity of the microstructure and making it possible to predict the b
ehavior of materials under similar conditions is proposed. (C) 1998 Am
