MEMS-Based in situ electron-microscopy investigation of rapid solidification and heat treatment on eutectic Al-Cu

In situ transmission electron microscopy as a toolbox for the emerging science of nanometallurgy

“…To assess the feasibility of melting and dissolving the nanomaterial alloying agents in situ within the TEM, both systems were heated to 660 °C (the melting point of Al), and the temperature was maintained for 300 ms. The duration of 300 ms was chosen based on the findings of Dumitraschkewitz et al 39 to ensure that melting would occur and to reduce the thickening of the sample due to surface tension. Prolonged exposure to the liquid state increases the risk of spheroidization/balling of the sample.…”
