Abstract

Damascus steel is a type of steel with visible inhomogeneities on the surface, most often in the form of patterns produced in various ways. The paper discusses the features of producing Damascus steel by forging multi-layer packages. This method can be used for manufacturing weapons (blades, sabers, knives, etc.), as well as tools for pro-cessing various materials (leather, plastic, wood). The plates from different steel grades produced by machining are deoiled and alternately collected in a pile. The pile is compressed in a tool, whose structural elements have different coefficients of linear expansion. Such tool with a pile of plates is charged in a furnace to produce a monolithic workpiece by diffusion welding in non-oxidizing environment with two isothermal tempering periods. The produced monolithic workpiece undergoes free forging. The method makes it possible to ensure the quality of welding and to produce a solid workpiece of Damascus steel, regardless of the chemical composition of steel of the welded plates. The objective of this paper is to study the influence of thickness and number of nickel layers on the structure, hardness and wear resistance of Damascus steel, depending on the nickel content, and to improve the quality of products by applying thermomechanical processing operations. Experimental data support feasibility of adding 0.3 mm thick Ni plates to the package, whose one of the criteria is the highest content of α-solid solution, contributing to their high mechanical properties. The technical result achieved by using this method of producing Damascus steel is to reliably ensure the quality of welding, produce a solid workpiece without internal defects, regardless of the chemical composition of steels of the welded plates. Based on the foregoing, it can be concluded that the present invention has novelty and an inventive step.
