ABSTRACT:
Articles are fabricated by collating and heating precursor metallic sheets of different compositions. The collated stack of sheets is heated with an applied pressure for a time sufficient to interdiffuse them either partially to produce a controllably modulated structure or completely to produce a homogeneous structure. The sheets may be collated in a form, and may be deformed during or after heating. The composition and structure of the final article is controllably varied from location to location by varying the composition, arrangement, or thickness of the collated sheets. In one embodiment, reinforcements such as fibers are positioned between the sheets.
