AN INTERLAYERED STRUCTURE FOR JOINING DISSIMILAR MATERIALS AND METHOD OF JOINING BY FIRCTION OF SUCH AN INTERLAYERED STRUCTURE

摘要

An interlayered structure (100) for joining of dissimilar materials includes a first material substrate (110), a second material substrate (120) having a composition dissimilar from a composition of the first material substrate (110), and a plurality of interlayers (132, 136) disposed between the first material substrate (110) and the second material substrate (120), including a first interlayer (132) nearest to the first material substrate (110) and a last interlayer (136) nearest to the second material substrate (120). The first interlayer (132) has a composition selected to have a maximum solid solubility within the composition of the first material substrate (110) that is greater than or equal to the other interlayers (136) within the composition of the first material substrate (110), and the last interlayer (136) has a composition selected to have a maximum solid solubility within the composition of the second material substrate (120) that is greater than or equal to the other interlayers (132) within the composition of the second material substrate (120).
