Heterostructures produced through severe plastic deformation of multilayered systems: Steel-Ti and steel-Mg

Abstract

Abstract. The presented research encompasses the processes of manufacturing incoherent metal-to-metal composite materials based on a multi-layered system. The primary aim of the present research is to achieve heterostructured materials with small "hard" phase particles within the "soft" phase matrix. Particles of the "hard" material can be obtained as a result of the loss of their continuity, for example, due to severe plastic deformation effects, such as accumulative roll bonding or multi-stage deep wire drawing processes. The presented research results constitute the first stage of implementing the aforementioned research plan. Basic relationships between the parameters of the deformation process and microstructural changes, as well as rheological properties of the investigated components of multilayer systems, i.e., microalloyed steel, Ti, and Mg, were determined. For this purpose, channel die compression tests and multi-stage deep wire drawing (DWD) experiments were conducted. The microstructural examinations and mechanical properties of the produced materials have indicated directions for further research.
