  • Manufacturing metallic components having integrated crack stoppers
    Patent number: 10828722
    Abstract: This relates to a method of manufacturing a metallic component by additive layer manufacturing. The method comprises the step of providing a layer of granular metallic material. The layer of the granular metallic material is melted by a laser beam or electron beam which applies a defined scanning strategy, which is defined in such a way that a first region of the layer is melted before a second region of the layer such that during the subsequent solidification, residual stresses emerge in the first and the second region. These residual stresses act as integrated crack stoppers of the metallic component.
