Abstract
Methods of additive manufacturing a superalloy component are disclosed. In one method a powder bed of superalloy powder is selectively scanned with a focused laser beam in a line-by-line manner; and the spacing between adjacent scan lines is no more 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 of said component from the substrate. In a further method a superalloy component is formed on a substrate and the method includes Hot Isostatic Processing of the component wherein the mass of the substrate is reduced prior to the Hot Isostatic Processing. The methods may be combined in a multi-step process.
