Crystalline metal can be transformed into metallic glass by

Alloying

Pressing into thin plates

Slow cooling of molten metal

Very rapid cooling of a spray of the molten metal

Solution

Crystalline metal can be transformed into a metallic glass by very rapid colling of molten metal. On rapid cooling of molten metal gives amorphous solid which is nothing but metallic glass.
