A component and method of forming a component are disclosed. The component includes a cast alloy section and an additive manufacturing section secured to the cast alloy section. Both the cast alloy section and the additive manufacturing section form at least a portion of an outer surface of the component. The method of forming a component includes removing a portion of an existing component, the removing of the portion forming an open section in the existing component, forming an article through an additive manufacturing technique, the article having a shape and geometry arranged and disposed to fill the open section in the existing component, and securing the article within the open section of the existing component to form the component. Another method includes directly depositing a material, by an additive manufacturing technique, over a portion of the existing component.
