1 Cryogenic Recycling of Solid Trash Cryogenic recycling and processing Norman R. Braton Boca Raton, Fla. : CRC Press, c1980. UF SCIENCE LIBRARY -- -- TP482 .C76 Recycle Symbol Breaking up of waste Pulverization depends on Type of Material Temperature Effect on Failure Rate Strain Rate: How fast can you change the shape of on object without it breaking. This decreases for most materials as T decreases. You just observed that failure rate decreases with temperature. What happens, in general, to the strength of materials as T is lowered? A. Increases B. Decreases Embrittlement Material with no Embrittlement Transition--Dutile Material with Embrittlement Transition--most common in BCC metals--ships Stress at Failure Strength Polymers Thermo-plastic Van der Waals Forces Thermoset Covalent Bonds Elastomer Cross-linked (both Van der Waals Forces and Covalent Bonds
