MCQ
Crystalline metal can be transformed into metallic glass by
  • A
    Alloying
  • B
    Pressing into thin plates
  • C
    Slow cooling of molten metal
  • ✓
    Very rapid cooling of a spray of the molten metal
✓

Answer

Correct option: D.
Very rapid cooling of a spray of the molten metal
d
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.
