Abstract (en)
[origin: EP1013781A2] A die cast article composed of nickel base superalloy IN 718 is disclosed. The microstructure is characterized by an absence of flowlines and includes a fine average grain size, e.g., ASTM 3 or smaller. A method of heat treating the articles is also disclosed. Exemplary articles include gas turbine engine components, such as blades, vanes, cases and seals. <IMAGE>
