Abstract
An interlayered structure for joining of dissimilar materials, includes a first material substrate, a second material substrate having a composition dissimilar from a composition of the first material substrate, and a plurality of interlayers disposed between the first material substrate and the second material substrate, including a first interlayer nearest to the first material substrate and a last interlayer nearest to the second material substrate. The first interlayer has a composition selected to have a maximum solid solubility within the composition of the first material substrate that is greater than or equal to the other interlayers' solubility within the composition of the first material substrate. The last interlayer has a composition selected to have a maximum solid solubility within the composition of the second material substrate that is greater than or equal to the other interlayers' solubility within the composition of the second material substrate. At least one of the plurality of interlayers is a sintered powder interlayer.
