As-cast microstructure characteristics of K439B nickel-based superalloy thin- walled castings of different thickness
K439B is a new type of nickel-based superalloy with a service temperature up to 800 ℃. In the face of the demand for mass reduction of aircraft， the structure of its components is developing in the direction of thin-wall. Thus， it is necessary to study the microstructure of the K439B alloy thin-wall...
