Document Summary

Mse (cid:858)(cid:373)otto(cid:859: processing, structure, properties, performance. Classification of materials: metals, polymers, ceramics, composite. Advanced materials: biomaterials, electrical, **look up more in book. Six categories of material properties: thermal, mechanical, electrical, optical, magnetic, deteriorative. Chapter 2 atomic structure and interatomic bonding. Most important in determining properties of material. First shell = 1s shell 2 electrons. General principles in periodic table: bonding forces and energy curves prediction of properties, left hand side like to donate, right hand side wants to accept. Primary and secondary bonds: primary (cid:1005)(cid:1004)(cid:1004)s kj(cid:859)s/(cid:373)ol. Further apart on periodic table wants to be an ionic bond. Metal to metal = metallic: secondary (cid:1005)(cid:1004) kj(cid:859)s/(cid:373)ol. Look up force vs distance graph around 7 min in video. Crystalline vs. amorphous: metals prefer to be crystalline. Unit cells sc, bcc, fcc, hcp: we get other crystal structures by altering either the length of the sides or angles of the simple cubic structure, most complicated structure = triclinic systems.
