2. ΔT = 1,000,000 °C / s

3. Non-crystalline, amorphous structure No dislocations No grain boundaries High elastic limit High strength

4. Discovered (1960’s) California Institute of Technology William L. Johnson Atakan Peker Metals used: Copper Nickel Zirconium Beryllium Titanium

5. Golf clubs Fishing rods Car bumpers Aircraft skins Artificial joints Dies Cutting tools Others

6. Small dimensions (due to cooling) Raw materials expensive Approx. from $500 per pound Production expensive

7. HOT SPARKS FLY FROM A NOTCHED SAMPLE OF BULK METALLIC GLASS FRACTURED BY A BLOW FROM A PENDULUM FRACTURED SURFACE SHOWS EVIDENCE OF LOCAL MELTING
