Certain materials which are commonly seen as brittle may exhibit superplastic behavior under the proper conditions, and the ability to use superplastic forming methods on intermetallics and ceramics opens a realm of possibilities. By using unique processing techniques, superplasticity has been observed in such advanced materials as nickel silicides (Ni/sub 3/SI), yttria-stabilized tetragonal zirconia (YTZ) and an Al/sub 2/O/sub 3/-reinforced YTZ composite (Al/sub 2/O/sub 3//YTZ).
