Abstract:

The research program at MIT on the fundamentals of processing of inorganic matrix composites focuses on developing a basic understanding of solidification processing of metal matrix composites and the behavior and modification of interfaces. This understanding is applied to the development of processes for the manufacture of evaluation specimens which are used, in turn, to determine the microstructureprocessingmaterials properties relationships. Technical areas discussed in this report include Kinetics of Fiber Preform Infiltration Infiltration of Fibrous Preforms by a Pure Metal Intrinsic Toughness of Interfaces Between SiC Coatings and Substrates of Si or C Fiber Interfaces with Controlled Toughness as Mechanical Fuses to Isolate Fibers from Damage A High-Resolution Transmission Electron Microscopy Study of the SiC coated Graphite FiberAluminum Composite Wetting of Ceramic Particulates with Liquid Aluminum Alloys Wettability of SiC Particulates with Zn and Zn-Al Alloys Interface Chemistry of Inorganic Composite Materials Preparation of Boron-Containing Ceramic Materials by Pyrolicis of the Decaborane14-Derived- B10H12-Ph2POPPh2x-Polymer Non-Polymeric Binders for Ceramic Powders Utilization of Neutral and Ionic Species Derived from Decaborane 14 and Phosphorus-Containing Derivatives of Dacaborane 14 as Precursors to Boron- Containing Materials. aw
