In the realm of advanced materials, Intermetallic Matrix Composites (IMCs) have garnered significant attention due to their potential for high-temperature applications. This study systematically investigates the influence of various processing parameters on the microstructure and mechanical properties of IMCs. Utilizing a combination of powder metallurgy and subsequent heat treatments, samples were prepared under varied conditions. The microstructural evolution was meticulously examined using Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM), revealing distinct morphological changes as a function of processing parameters. Quantitative analysis demonstrated a direct correlation between processing conditions and the distribution, size, and morphology of the reinforcing phases. Mechanical testing, including tensile, compression, and hardness tests, was conducted to evaluate the resultant properties. The findings indicate that specific processing conditions can be optimized to achieve a desirable balance between ductility and strength. Notably, a unique set of parameters was identified that yielded an unprecedented combination of high strength and ductility, challenging the conventional trade-off paradigm in composite materials. This research underscores the critical role of processing in tailoring the microstructure and, consequently, the mechanical performance of IMCs, paving the way for their application in demanding environments. |
