Abstract
This final report covers work in three areas. In the area of modulated microstructures hardened steel, the final result was a sample which had a strength of 270 ksi and a fracture toughness of ksi sq. root(in). These properties were obtained with a 50% soft layer and a special 0.28%C alloy (Ni, Co, C, Mo, V). In the area of catalytic properties of surface sites, work is reported on the subjects of CO and NO reactions on chromia supported on silica, hydrocarbon synthesis over bimetallic clusters, characterization of surfaces by ESCA, and electrode reaction studies. The topic of imaging through the use of surface acoustic waves was addressed by considering three different types of devices: a separate media configuration employing high-resistivity silicon wafer and a lithium niobate substrate, a monolithic device employing the silicon and lithium niobate, and a separate media configuration where the silicon continuum is replaced by a pn diode array, In the course of research on the monolithic devices, a technique was developed for achieving a tremendous enhancement in photon detection sensitivity by using a pulsed bias supply.
