The aim of the present review is to summarize recent achievements in development ultrafine-grained austenitic/ferritic stainless steels processed by large strain deformation. Various aspects microstructure evolution and its effect on properties are considered. paper starts from an overview various methods deformation that successfully used for producing metallic materials. Then, structural mech...

Abstract The article focuses on the Direct Drive Rotary Friction Welding of ultrafine-grained copper rods, which feature increased mechanical properties and good electrical properties, yet are limited in size. use UFG metals is often by too small dimensions semi-finished elements produced SPD methods. Therefore, production finished machine parts from currently economically unjustified. Dismissa...
