Abstract Scope |
Production of many advanced materials, such as steel, high-temperature superconductors, and rare-earth permanent magnets, involves a peritectic transition. However, due to a significant compositional dependency and variable morphology, understanding and anticipating the growth modes of peritectic alloys has proven challenging. Here, we select the Ag-Zn as a model system to investigate the mechanisms of the peritectic transition. We study how the primary intermetallic phase transforms into the peritectic phase under slow growth conditions in directional solidification. Our efforts are made possible by x-ray microtomography, which enables us to obtain detailed three-dimensional information and avoid sectioning artefacts. Based on our experimental findings, we propose an original growth mechanism for the formation of the peritectic phase from the primary phase under peritectic transition. |
