Material Science and Engineering for M.E.57017Structure of Crystalline SolidsPrepared by:Engr. Dexter Lyndon Sabusap
Objectives1.Describe the difference in atomic/molecular structure between crystalline and noncrystallinematerials.2.Draw unit cells for face-centered cubic, body-centered cubic, body-centered tetragonal, andhexagonal closed-packed crystal structures.3.Derive the relationships between unit edge cell length and atomic radius for face-centeredcubic, body-centered cubic, body-centered tetragonal, and hexagonal closed-packed crystalstructures.4.Compute the densities for metals having face-centered cubic, body-centered cubic, body-centered tetragonal, and hexagonal closed-packed crystal structures.
Crystalline MaterialAcrystalline materialis one in which the atoms are situated in arepeating or periodic array over large atomic distances; that is, long-range order exists, such that upon solidification, the atoms will positionthemselves in a repetitive three-dimensional pattern, in which eachatom is bonded to its nearest-neighbor atoms.
