摘要：Methods of additive manufacturing a superalloy component are disclosed. Inone method a powder bed of superalloy powder is selectively scanned with a focusedlaser beam in a line-by-line manner; and the spacing between adjacent scan lines is nomore than twice the layer thickness being formed. In another method a compressive
stress treatment is applied to the surface of the final component prior to separation ofsaid component from the substrate. In a further method a superalloy component isformed on a substrate and the method includes Hot Isostatic Processing of thecomponent wherein the mass of the substrate is reduced prior to the Hot IsostaticProcessing. The methods may be combined in a multi-step process.
