Аннотация

Samples of Al-Ce-Fe-Ni-Zr alloy were obtained by selective laser melting at scanning speeds of 700–1900 mm/s. The structure of the samples is eutectic: a solid solution based on aluminum is located inside intermetallic cells. A coarser eutectic structure with coarser cells is observed at the cell boundary. The microhardness of the samples was HV0,1 = 115–170, the tensile strength was 370–475 MPa, and the ductility was 10–23%. Residual thermal stresses <250 MPa were observed in the samples. An increase in energy density contributed to a decrease in strength characteristics, an increase in elongation, and a decrease in residual stress.
