Glassy Metals

THE SUPERHERO OF GLUES:
Cyanoacrylate ( C5H5NO2(I)) forms strong bonds when it comes in contact with hydroxide ions ( OH-(g)) which is found in water, when the adhesivecomes in contact with the water vapor it hardens, changing from liquid to solid.
Its powerful electron-attracting groups’ form chains form chains of molecules, linkedtogether. These chains form a rigid, plastic net that holds any molecules it comes in contact with.

SCI- FI METAL:
Scientists have produced an amorphous, or glassymetal that acts like plastic, but is stronger than titanium. To produce the metal, elements are mixed together then melted together, and the cooled quickly.
A glassymetal is stronger than regular metals because its atoms do not cool into a crystalline pattern. Instead, it has a random arrangement of atoms, which makes it able to transferenergy faster and last longer than other metals.



QUESTIONS:
1. How are glassy metals produced?

They are produced in laboratories, first the elements aremixed together, then melted together and finally cooled down very quickly.
2. Research the benefits and disadvantages of using glassy metals in the industry?

AdvantagesDisadvantages
 2-3 stronger than conventional alloys
 Less metal needed, less product weight
 Formed like plastic
 Made into foam
 Resist deforming, Absorb lessenergy  Expensive
 Metalworking factories need retooling
 Brittle, Shatters like glass








3. Look for information on other materials produced with newtechnologies.
Cell phone cases, camera bodies, golf club heads, folding knives, weapons, tennis racket frames, artificial hips & knees, PDA’s, laptops, surgical blades
