Solidification Processing & Mechanical Behavior of Ta-W/Wp Refractory Metal Base Composites.

Abstract

In this research program, two solidification processing technique, that is spray atomization and deposition, and low pressure plasma spraying (LPPS) were both experimentally and theoretically studied for processing refractory metals and alloys such as tantalum alloys and tungsten, and refractory intermetallic composites, such as SiC reinforced MoSi2 composites. In this final report, the aforementioned experimental and numerical results are described and discussed in four respective sections, which are numerical analysis of droplet-gas interactions in spray atomization of Ta-(2.5w) alloy; low pressure plasma spraying of tungsten; numerical analysis of porosity evolution during low pressure plasma spraying of tungsten; and microstructure and behavior of low pressure plasma deposited SiC-reinforced MoSi2. In addition, the work on the elevated temperature deformation of 6061 aluminum alloy and SiC particulate reinforced 6061 aluminum composites is also included. jg p.1
