5. The first three peaks in an x-ray w-29 scan are at 9 = 19.20, 22.40, and 32.6, respectively. (a) Identify the planes. (b) Explain any missing peaks between 9 = 0 and 32.60. (c) What is the Bravais lattice? (d) What is meant and the value of the rocking curve? ) What is a reciprocal space map and what does it tell you about the crystal?6. (a) What is the line density along the [111] direction in FCC Al if rAl = 0.143nm? (b) What is the planar density for the (111) plane? (c) If a stress of 101bs/in is applied along the [1-10], what is the Schmid Factor? (d) If the slipping threshold is 51bs/ in', will slipping occur
