... theory estimates the strain dependence of the stored energy, and the ratio of stored to expended energy. The experimental data of Adam and Wolfenden, which include values of stress, strain ( ε ), stored energy ( E s ), and expended energy ( E w ) for unidirectionally solidified eutectic alloys Al-Al 3...

... An extensive literature has emerged on the flow and fracture behavior of aligned eutectic composites. However, there have been few attempts to systematically record and compare fractographic features in eutectics as a function of microstructural variables (for example, interfiber spacing...

... A titanium-21 weight percent germanium eutectic alloy was unidirectionally solidified at two different rates to produce a composite material strengthened by intermetallic Ti 5 Ge 3 fibers. The higher solidification rate produced a composite with fibers of finer diameters. The fracture behavior...

... The eutectic Ni(Cr)-TaC has been directionally solidified to yield a fibrous composite. The material was studied in strain-limited low-cycle fatigue at room temperature and 1000°C. The eutectic with brittle fibers and a ductile matrix was found to obey the Coffin-Manson law at both temperatures...

... The eutectic alloy Ag-32 atomic percent Mg has been directionally solidified at rates ranging from 0.8 to 27.7 cm/h to produce an aligned lamellar structure. The alloy, consisting of 40 volume percent AgMg and 60 volume percent of a solid solution of approximate composition Ag-27 atomic percent...

... Composites formed by unidirectional solidification of eutectic alloys usually exhibit a preferred crystallography of both phases and low-energy interfaces. Because of this, eutectic composites have been found to exhibit excellent microstructural stability and property retention after elevated...

Replicas gave somewhat limited data due to the presence of subtle artifacts created during metallographic preparation, while emission microscopy gave considerably more topographical definition than that obtained by optical methods. Microtomed sections also proved to be of little value...
