Abstract:
A method for fabricating a nonplanar article, comprising the steps ofselecting a useful metallic composition;selecting a precursor of the useful metallic composition, the precursor comprising at least two metallic sheets including a first metallic sheet having a first composition and a second metallic sheet having a second composition different from the first composition, the first composition and the second composition each being different from the useful metallic composition;providing the first and second metallic sheets;collating a sequenced stack of the at least two metallic sheets on a form defining the shape of a final, nonplanar article, wherein at least a portion of each of the metallic sheets is nonplanar; andheating the stack to interdiffuse the collated stack of sheets to form an interdiffused structure having the useful metallic composition and the shape of the nonplanar article.
