Nanoscale structural evolution of gallium-copper, gallium-zinc, and gallium-bismuth alloys
The investigation demonstrates the presence of nanostructures in 1, 2 and 5 wt% GaCu alloys in the measured SANS range at 30 °C. Interestingly, these structures do not persist at elevated temperatures of 60 and 90 °C, indicating thermally driven homogenisation. In contrast, GaZn and GaBi alloys at similar concentrations do not exhibit any nanostructures, irrespective of the measured temperatures, highlighting alloy-specific structuring behaviour. These results provide new insight into nanoscale organisation within LMs and inform rational design for catalysis, electronics, and additive manufacturing applications.
