Cooling High-strength

Belite containing abundant alpha form, alite with high birefringence High temperature and quick cooling high strength (Ono, Kawamura, and Soda, 1968)... 

Alloys containing nickel and/or aluminum have high strength and the impact data may exhibit scatter if the cooling rate or composition has not been closely controlled. 

Polymer High MW (>10,000) Tg usually < RT Physically crosslinks on cooling Strong Strength Hot tack Viscous loss —> peel force... 

When this impure iron cools, the resulting solid is called pig iron or cast iron. It is quite brittle and is not useful if high strength is needed. 

When X = Y, as in polyethylene, poly-(tetrafluoroethylene), polyisobutylene, and poly -(vinylidene chloride), the polymers are highly crystalline products with sharply definable melting points (except for polyisobutylene, which crystallizes readily on stretching but with difficulty on cooling). Oriented specimens of high strength may be obtained, exactly as in the crystalline condensation polymers. 

Sulfur concretes (SC) are basically simple materials, made by mixing sulfur plus certain additives with heated mineral aggregates. On cooling, SC sets to give a high-strength material with superb corrosion resistance.
