Sketch this plane within a unit cell. b. How many atoms are on the plane you drew inside the unit cell? c. Estimate the area of the plane d. Calculate the area atomic density e. If there is one vacancy per 1012 lattice points at 273K, what is the partial atomic occupancy of each lattice point? f. If you are asked calculate the number of vacancies present at 600K, what additional information do you need? 12. Dislocation motion occurs largely along close-packed directions and planes. First, compare the FCC & BCC structures: a. Describe any close packed planes b. Describe any close packed directions c. If the ductile-to-brittle transition at low temperatures is related to the number of close-packed directions and planes, do you expect BCC or FCC metals to have greater ductility? d. Magnesium and other HCP metals are brittle. Does your analysis from 12.c. support this observation? 13. A tensile test is performed on a ductile sample. The first 1% of strain is elastic with a modulus of 100E9 Pa, at which point plastic deformation begins. The tensile strength of 1.1E9 Pa is determined at 9% strain, while failure occurs at a stress of 9E8 Pa and strain of 18%. a. Sketch the complete stress-strain cycle b. Estimate the toughness in units of J/m3.
