MATERIALS AND STRUCTURES. APPLIED METALLURGICAL RESEARCH PROGRAM

Abstract

Research programs were undertaken on refractory carbides and on the process of densification of metals. The end result of the carbide program will be an understanding of how the physical and mechanical properties of carbides can be optimized by basic understanding of the processes involved in fabrication. The particular carbide systems studied are those of maximum interest for missile and space applications. Suitable equipment for this work has been designed and purchased. Materials are on hand and future progress will depend on obtaining suitable facilities. Preliminary studies on densification of tin, which can be used as a model for the refractory metals, suggest that densification occurs by a plastic flow mechanism characterized by a yield point. Further experiments are in progress to confirm this conclusion. (Author)
