Studium vlastností materiálů zpracovaných procesem Accumulative Toll Bonding

Abstract

This Ph.D. thesis deals with common used aerospace materials, their advantages and possibilities for Accumulative Roll Bonding process. The study focus on metal sheet materials such as a corrosion resistant steels, chromium-nickel based alloys, cobalt alloy, aluminum alloy, titanium and titanium alloy. Material properties and related stress-strain material characteristics selected materials present first part of this study. Comparison material’s hardening models per Krupkowki (Swift) and Hollomon laws, their usability to definition/correlation of stress-strain curve for wide spectrum of used materials were included to the first part of this study. This investigations can be used to application within CAE codes, commercially known as PampStamp 2G. Consequently, Accumulative Roll bonding process were selected to testing possibilities to formation weld joint and increase mechanical properties related to grain size refinement for selected materials. Basic parameters and influence Accumulative Roll Bonding process application is described by second part of this Ph.D. thesis.
