| Abstract Scope |
The incorporation of nano-scale particles in an Al matrix is a promising approach to improved ambient and elevated temperature mechanical properties. In situ processing methods, where particles are created directly in the melt via direct reaction, have been demonstrated to exhibit improved particle/matrix interface stability and easier incorporation within the matrix. It was also found that applying low electrical currents during solidification results in refinement of the microstructure. However, the ability to reliably control critical mechanical property-dependent particle characteristics remains a barrier to large-scale processing. This talk will describe a multi-modal, multi-scale investigation to analyze the formation mechanisms, morphology, and microstructure of Al-TiC metal matrix composites processed by different in situ processes. By combining synchrotron-based X-ray nanotomography with scanning and transmission electron microscopy, we visualize in over five orders-of-magnitude of length-scale the TiC nanoparticles and Al3Ti intermetallics. The results offer general guidelines for the rational synthesis and processing of Al-MMNCs. |
