Researchers discover spontaneous liquefaction of solid metal–liquid metal interfaces in colloidal binary alloys

Researchers have discovered a spontaneous liquefaction phenomenon at the solid-liquid interface in colloidal binary metal alloys. They found that surface atoms in solid metals can break away and melt even at temperatures far below the metal’s melting point, with significant implications for metallurgy. This process was observed in copper-gallium systems using transmission electron microscopy, revealing unexpected oscillations at the atomic level. Such findings may lead to new alloy processes and improved 3D printing. For further details, refer to the full article here:
