| Abstract Scope |
Improving the fracture toughness of ceramics has been an active area of research since the advantages of advanced ceramics over metals (higher strength and stiffness, lower density, elevated operating temperatures, and superior corrosion resistance) were first recognized. Success has been achieved through extrinsic strategies, including defect engineering, secondary particle reinforcement, and fiber-reinforced ceramic matrix composites. However, these strategies face significant manufacturing challenges, as they depend on skilled labor and specialized equipment, limiting their scalability and industry adoption. In this project, we combine reaction sintering with non-equilibrium hot forging to manufacture intrinsically tough and cost-effective boron carbide ceramics. By integrating micro-alloying and hot forging, we anticipate generating a significant density of dislocations due to the facilitated dislocation movement resulted from aluminum doping and substantial plastic deformation of the ceramic during forging. Our materials processing and characterization efforts are supported by physics-based modeling of dislocations and data-driven predictive modeling of processing-property correlations. |
