Regularities of defect formation at additive electron-beam manufacturing of polymetallic samples
The regularities of defect formation in polymetallic materials of various systems obtained by the method of electron-beam additive technology with the process parameters variation from the optimal values are investigated. It is revealed that depending on the material selected for the metal and alloy samples formation there is nucleation of defects which differ in structure and influence on mechanical properties. In the samples from the pair of metals with high solubility in the solid state and the ability to form intermetallic compounds, determined by the state diagram, the defects are formed in the form of cracks and stratifications. Samples of all systems can form heterogeneous distribution of the system components due to irregularity of wire filament feeding, filament underheating or substrate overheating.
