Abstract

The paper utilized vacuum induction melting furnace to smelt three kind of nickel base superalloys as the research subject. It investigated the effect of revert addition on microstructure and mechanical properties of K418 Ni-based superalloy by means of XRD phase test, microstructure observation and tensile test. The original microstructure of material showed dendrite structure, the main phase of K418 is Cr1.12Ni2.88, strengthening phases are Ni3Al, Ni0.9Nb0.1 and Al0.5Fe0.5. The tensile experiment showed when recycled alloy proportion is less than 50%, it had slightly influence on mechanical properties of materials, and it has a good cyclic utilization rate. In view of the high cost of the superalloy, its cyclic utilization is friendly to the environment and it reduces the waste of resource.
