| Abstract Scope |
MAX phase materials, such as Ti3SiC2, are a family of ternary carbides and nitrides that exhibit some of the desirable properties of both metals and ceramics. At room temperature, when mechanically deformed, it exhibits elastic deformation followed by a brittle failure. At high temperatures (>1000°C), however, it exhibits ductility comparable to that of metals. This study aims to explain this brittle to ductile (BTD) transition using tensile and flexure tests coupled with physics-based Crystal Plasticity (CP) modeling. SEM characterization is conducted on samples tested under the two modes of loading at various temperatures ranging from room temperature to 1200°C to interpret the modes of deformation. Utilizing the SEM observations, the CP is tuned and used to simulate the observed deformation behavior and identify the mechanisms responsible for the BTD transition. |
