| Abstract Scope |
Materials with hard ceramic particles in soft matrices have been manufactured to enhance the strength for applications at elevated temperatures. We report a significant enhancement in hardness in Ti-B4C and alloyed steel-B4C composites manufactured using a reactive sintering process. The decomposition of B4C during sintering releases boron and carbon, and produces a composite containing complex boride and carbide with a softer matrix. We observe the formation of TiB and TiC in Ti matrix. For alloyed steel, Mo segregates to Fe-boride phase and forms Fe-Mo-boride in addition to Fe-carbide phases in Fe matrix. In this presentation, we will discuss the strengthening mechanisms, and correlate the mechanical properties with the microstructure. |
