ATOMIC STRUCTURE AND INTERATOMIC BONDING
Electrons in Atoms
2.1 Cite the difference between atomic mass and atomic weight.
Atomic mass is the mass of an individual atom, whereas atomic weight is th
IMPERFECTIONS IN SOLIDS
Vacancies and Self-Interstitials
4.1 The equilibrium fraction of lattice sites that are vacant in silver (Ag) at 700 C is 2 106. Calculate
the number of vacancies (per meter cubed) at 700C. Assume a dens
5.1 Briefly explain the difference between self-diffusion and interdiffusion.
Self-diffusion is atomic migration in pure metals-i.e., when all atoms exchanging positions are of the same
MECHANICAL PROPERTIES OF METALS
Concepts of Stress and Strain
6.1 Using mechanics-of-materials principles (i.e., equations of mechanical equilibrium applied to a freebody diagram), derive Equations 6.4a and 6.4b.
