Abstract

In some cases, in situ composites may be fabricated by mechanical working even when they contain phases which are inherently "mechanically incompatible" in bulk form. An extreme case is provided by composites containing low volume fractions of "brittle" chromium. The initial microstructure plays an important role in the fabricability of these composites and several examples of this are provided by our work. During wire drawing, interphase spacing is reduced in an axially symmetric manner irrespective of whether or not a lamellar or ribbon-like morphology is developed. The reduction in interphase spacing with rolling strain is similar to that observed during drawing in spite of the externally imposed plane strain conditions accompanying deformation by rolling. © 1984.
