| Abstract Scope |
This work presents the results of theoretical and experimental analysis of a laser deposited two-component material created from powder composition of aluminium bronze and SS 316L at the ratio 3:1. Microstructure parameters and mechanical properties (yield and ultimate stresses, Young's modulus, Poisson's ratio, microhardness) and thermal expansion coefficients (TECs) were measured for the binary alloy and compared with pure aluminium bronze and stainless steel. The linear TEC amounted 1.362 1/K what is slightly lower than TECs of initial materials. Ultimate tensile stress amounted 713.7 MPa. A main field of practical application of such dual materials is operating under external forces in extreme temperature conditions and aggressive alkaline and salt atmospheres. Such alloys also can be used as a general or intermediate components for additive manufactured functionally graded Cu-Fe system materials applied in aerospace and nuclear industries, processing equipment and electronic components producing. |
