Abstract Scope |
Metal matrix composites (MMCs) are the future of materials in the transportation and aerospace industries due to their possibility of overall weight reduction by improving strength, wear resistance and high temperature tensile properties. Creating the reinforcement of MMCs via in-situ methods lead to enhanced matrix-particle bonding, particle size distribution, and reduction in contamination as compared with ex-situ processes, and therefore improved mechanical properties. This research focuses on MMCs made using salt-flux reaction synthesis, a process which creates carbides (e.g. TiC) via a redox reaction between the metal melt and a metal-bearing flux (e.g. K2TiF6), then the liberated metal reacts with carbon to precipitate carbides in the melt. Particle morphology of this method is highly dependent on processing conditions, such as matrix composition. Nanotomography was performed at the synchrotron at Brookhaven National Lab to visualize the 3D morphology of the formed carbides under varying Si loading in an Al matrix. |
