This project deals with various aspects of the multilayer structure during hot package rolling in the multilayer materials with over 1000 layers, as exemplified by a multilayer structure composed of the 30HGSA and 08H18 steels. The subject of analysis was the structural state maps of steels that make up the researched structure. The results of research conducted by means of the micro X-ray spectroscopy and microdiffraction analysis establish the causes of the structural damages in the samples, which are primarily related to the ongoing flattening diffusion of the alloying elements, and serve as the basis for a model of multilayer materials recrystallization, based on a hypothesis postulating that the interlayer boundary is where new dynamic recrystallization grains form. Recommendations are given on performing hot package rolling when producing multilayer materials.
Key words: multilayer metal materials / hot package rolling / dynamic recrystallization / structural state maps
