Which outcome occurs when rapid cooling causes a metallic glass alloy to solidify below its glass transition temperature?

💡 Explanation

When rapidly cooled below the glass transition temperature, a metallic glass alloy experiences structural relaxation because atomic mobility decreases drastically, causing a massive, exponential increase in viscosity. Therefore viscosity increases exponentially rather than nucleation, decreased density or improved ductility, which all require different kinetic or thermodynamic conditions.
