Abstract Scope |
Presented are the fabrication techniques and parameters for Ni-Cr (Nickel-Chromium) and Fe-Cr (Iron-Chromium) alloys to produce tailored grain size samples in order to understand the influence of high-temperature corrosion performance. Fe-Cr and Ni-Cr were fabricated via the arc melting method, then were cooled at different rates to ascertain the effects on grain size as a function of cooling rate and alloy composition. Additionally, post-synthesis heat treatments were employed to grow grain sizes and homogenize the alloy compositions. Electron microscopy methods were leveraged to characterize the sample microstructural evolution. In addition, the effect of the grain size on molten FLiNaK (Li-F-NaF-KF) salt dealloying of Ni20Cr (wt%) at 600 °C was also studied. These samples were targeted for simultaneous irradiation and corrosion experiments to observe the microstructural evolution of these tailored samples. |
