Abstract : Combustion Joining of refractory materials has great potential for low cost, rapid fabrication of composites, esp. for some materials that are difficult or impossible to join using more conventional techniques: Rapid combustion reactions provide a unique set of conditions for synthesizing functionally graded layers: short reaction times (1 10 s) allow the desired functionally graded material structure to be maintained Demonstrated the concept for joining of SiC-Al-alloy using a combustionbased approach Need to determine optimum reaction layer composition and heat-treatment conditions to form various phases: - Ti3SiC2 (ductile), Si(Al)CO, TiC-SiC-Al New press set-up /die design implemented to produce optimized materials for sub-scale ballistic tests.
