Proper0es (mechanical, thermal and electronic) of metals, polymers, ceramics, and electronic materials. Correla0ons of these proper0es with : • their internal structures (atomic, molecular, crystalline, Micro‐ and macro) • service condi0ons (mechanical, thermal, chemical, electrical, magne0c, and radia0on) • processing. The History of Civiliza4on is a Story of Materials Discovery, Inven4on and Use • From the stone age to the iron and bronze ages we characterize our command of nature by the materials we use. • Now in the era of high strength steel skyscrapers, high tech Shanghai, space travel (China), nanomaterials, biomaterials, energy materials • Materials ENABLES progress and helps solve BIG problems Structure, Processing, & Proper0es (d) 600 500
