Heating-Induced Recrystallization in Copper Subjected to High-Rate Deformation during the Collapse of Massive Cylindrical Shells under Explosion Loading

Autor: N. Yu. Frolova, A. E. Kheifets, I. V. Khomskaya, V. I. Zel’dovich

Publikováno v: Physics of Metals and Metallography. 121:548-553

The recrystallization process in copper subjected to high-rate compression deformation by collapsing a massive cylindrical shell into a cylinder has been studied in this work. Recrystallization occurs in two stages due to the peculiarities of the def
