Example of the methodology for producing heterostructural systems using plastic deformation

Abstract. The study specifically examines the changes in the properties of the investigated systems as metal-to-metal composites and their constituent components. These heterostructural systems were crafted from microalloyed steel, reinforced with rheological non-uniformity due to the presence of Ti or Mg hcp phases. The influence of total deformation on the continuity of hcp layers and the degree of refinement of the matrix microstructure, i.e., microalloyed steel obtained through continuous recrystallization, was examined. The analysis delves into various strengthening mechanisms within the studied heterostructural systems, with particular emphasis on the strengthening effect resulting from the presence of low-plasticity hcp phases and their interaction with the entire system. The results of rheological studies conducted using channel compression tests and deep wire drawing (DWD) are presented. Microstructural studies have shown not only changes in the microstructure of the constituent materials but also the mutual interaction of these changes, directly affect the mechanical properties of the investigated heterogeneous materials.
