ABSTRACT
In the early 1960s it was recognized that directional solidification of eutectic alloys was a feasible method for producing composites, so called eutectic or insitu composites. The applications were widespread, ranging from structural uses (high strength modulus, low-density Al composites, heat-resistant Ni composites) to nonstructural uses (optical and magnetic anisotropic functions). These studies included microstructure and control of microstructure, physical and mechanical properties, environmental response, thermal and mechanical instability, and development of new eutectic systems. Results and technological directions have been reviewed in the four periodical meetings focused on this subject; In-Situ Composite-I (1973), In-Situ Composite-11 (1976), In-Situ Composite-ill (1979), InSitu Composite-lY (1982). At each meeting, mechanical properties have been reviewed on the basis of information obtained during the respective intervals. In addition, there are two excellent summaries of property data for high-temperature applications (Thompson and Lemkey, 1974) and of modeling of mechanical behaviors (Mclean, 1983).
