Abstract: A method of welding a component and a treated component are provided. The method comprises an initial heat-treating of the component comprising a substrate. The method further comprises removing a portion of the substrate to form a treatment region comprising an exposed surface. The method further comprises buttering the exposed surface with a first filler additive to form a weld metal adjacent to the fusion line comprising an easy-to-weld alloy. The method further comprises welding the component with the easy-to-weld alloy and a second filler additive. The first filler additive comprises a sufficient amount of each of Co, Cr, Mo, Fe, Al, Ti, Mn, C and Ni to form the easy-to-weld alloy, when welded with the hard-to-weld base alloy.

Abstract: A method of making a pre-sintered preform, including forming a pre-sintered preform by a binder jet additive manufacturing technique. The binder jet additive manufacturing technique includes depositing a first powder layer including a first powder and a second powder followed by depositing a first binder at a pre-determined location of the first powder layer. The binder jet additive manufacturing technique also includes depositing a second powder layer over at least a portion of the first powder layer followed by depositing a second binder at a pre-determined location of the second powder layer. At least a portion of the first binder and at least a portion of the second binder is cured forming a green part. The green part is then densified to form a pre-sintered preform near net shape component.

Abstract: Casting methods and articles are disclosed wherein a molten first material is introduced into a mold which distributes the first material to form a first region of the article where it is subjected to a first condition suitable for growing a first grain structure, forming the first region of the article. A molten second material, compositionally distinct from the first material, is introduced into the mold to form a second region of the article. A hybridized material is formed by intermixing a first portion of the second material with the second portion of the first material. A second portion of the second material is subjected to a second condition suitable for growing a second grain structure distinct from the first grain structure, forming the second region of the article. The first region and the second region are integrally formed as a single, continuous article with a hybridized region formed between.
