Thermal stability of Cr–Cr3Si eutectic microstructures
چکیده انگلیسی

The thermal stability of Cr–Cr3Si lamellar eutectic composites was investigated at temperatures up to 1400 °C. In drop-cast Cr–Cr3Si, coarsening was found to be interface controlled. The coarsening rate could be reduced by microalloying with Ce and Re, two elements which were chosen because they were expected to segregate to the Cr–Cr3Si interfaces. Similarly, directional solidification, which is also expected to lower the Cr–Cr3Si interfacial energy, was found to dramatically decrease the coarsening rate.
