How a liquid metal can turn solid steel into brittle glass
In short: Watch as gallium transforms the structural integrity of aluminium. This video explores liquid metal embrittlement, a physical phenomenon where ductile metals lose their strength and become brittle upon contact with specific liquids.
Liquid metal embrittlement is a significant industrial hazard. It occurs when a ductile metal, such as aluminium, comes into contact with a liquid metal like gallium. Rather than a chemical reaction, the process is physical: the liquid gallium infiltrates the microscopic spaces within the aluminium's internal structure.
This transition from ductile to brittle is a critical concern in manufacturing and other engineering fields where these materials might interact. The video demonstrates the practical risks and the mechanics of how liquid metals can compromise structural stability.
