摘要：Articles are fabricated by collating and heating precursor metallic sheets(44,46) of different compositions. The collated stack of sheets (44,46) is heated with anapplied pressure for a time sufficient to interdiffuse them either partially to produce acontrollably modulated structure or completely to produce a homogeneous structure.The sheets (44,46) may be collated in a form (42), and may be deformed during or afterheating. The composition and structure of the final article is controllably varied fromlocation to location by varying the composition, arrangement, or thickness of thecollated sheets. In one embodiment, reinforcements such as fibers (62) are positionedbetween the sheets (44,46).
