On the feasibility of producing locally modified metallic materials with controlled gradient of properties

Abstract

Metallurgy and engineering endeavours to develop and implement advanced technologies to save metal and create new metallic materials with improved characteristics. These scientific and technological activities include improvements to existing materials as well as the development of new materials by various methods. One such method is the creation of iron-based materials with a gradient of properties along the cross-section, obtained by locally modifying a given volume of the formed billet by filling the structure with heat-resistant, high-strength, dispersed phases. This paper describes the course and results of a number of experiments on the formation of a gradient of properties in steel castings of various compositions, and analyses the results of experiments on the creation of such materials.
