Method to produce an additively manufactured, graded composite transition joint

An additively manufactured, graded transition joint (AM-GCTJ), comprising:

• a first alloy A;
• a second alloy B;
• a transition joint, wherein a larger concentration of the first alloy A is disposed at a first end of the transition joint, which also has a lower concentration of the second alloy B, and a larger concentration of the second alloy B is disposed at a second end of the transition joint, which also has a lower concentration of the first alloy A;
• and
• a gradient composite transition of the first alloy A and the second alloy B is disposed between the first end of the transition joint and the second end of the transition joint, wherein the gradient composite transition of the first alloy A and the second alloy B includes a graded transition of the first alloy A and the second alloy B from the first end of the transition joint to the second end of the transition joint, and wherein the gradient composite transition includes a grating or lattice pattern of the first alloy A that includes pores with a size that increases from the first end of the transition joint to the second end of the transition joint.

An additively manufactured, graded transition joint (AM-GCTJ), comprising:

• a mixture of a first alloy A and a second alloy B;
• the first alloy A includes a grating or lattice pattern having a graduated density of the first alloy A, the grating or lattice pattern having a first end and a second end, and the grating or lattice pattern includes at least one pore, the at least one pore has a pore size diameter in a range from between about tens of micrometers to about hundreds of micrometers;
• and
• the grating or lattice pattern having a density of the first alloy A on the second end that is denser than the the density of the first alloy A at the first end, and the density has a graduated volumetric ratio from 0% to 100% by at least one of increasing the pore size from the second end to the first end or reducing the grating or the lattice pattern density as layers are additively built up from the second end towards the first end, and wherein the second alloy B is added to the grating or lattice pattern to form a composite with the grating or lattice pattern, wherein the composite has a concentration of the second alloy B from about 0% of the second alloy B at the second end to about 100% of the second alloy B at the first end of the AM-GCTJ.
