Description
Summary:Currently, direct laser deposition is a key research area since use of this technology is distinguished by cheapness and the possibility of preparing an object of almost any shape. However, numerous aspects of material manufacturing technology and structure formation remain unstudied. The process of preparing polymetallic specimens consisting of layers of alloys Inconel 625 and EP741 is considered. A polymetallic specimen microstructure is extended nickel solid solution crystals. Element distribution in a grain boundary zone shows a smooth change in composition as a result of element diffusion from Inconel 625 alloy into EP741, and conversely. Layer microhardness varies from 300 to 500 HV with transition from Inconel 625 alloy into EP741
