Abstract:

The objectives of this program were 1 to investigate and determine the processing conditions required to achieve desired microstructures and mechanical properties in advanced aerospace materials, 2 to implement and use analytical models for process design in the Materials Processing Laboratory, 3 to validate analytical models by physical modeling, and 4 to create a center of excellence for materials processing. Primary emphasis was given to composites and high temperature materials used in advanced engines and structures. Materials of various types and compositions were studied. In several cases, a full fledged Processing Science approach was utilized, in which the material was fully characterized in terms of microstructural and flow behavior, the proposed processing method was modeled analytically, the actual processing was carried out in the Materials Processing Laboratory MPL and the analytical model was validated with experimental measurements. In other cases some of these steps were eliminated when the material or process was well understood.
