All the promising Mo-Si-B-X alloys developed so far contain a mixture of Mo-solid solution and brittle intermetallic phases. For further advances to occur, a full understanding and control of the properties of the Mo-rich solid solution is critical. The poor low temperature ductility of the solid solution phase and the catastrophic intermediate temperature oxidation resistance continue to be key problems in the development of Mo-Si-B alloys. We propose to solve these two critical problems through novel alloying strategies and developing new alloy compositions. Mo-Si-B-X alloys maybe fabricated both by casting as well as through a powder metallurgical route. Recent studies on mechanical alloying followed by compaction and sintering have shown considerable promise in obtaining uniform microstructures in these alloys while maintaining good mechanical properties. We propose to optimize the microstructure through modeling studies.
