Outside the unit cell, sketch the atomic configuration for the (111) plane for FCC aluminum. Clearly indicate which atoms (if any) are touching. Clearly indicate the close packed directions, if any, on this specific plane and give the Miller Indices for each one. You must use the coordinate system illustrated below to index the clos packed directions on this plane.

Why is iron generally harder and have higher yield strength (σy) when it is alloyed with carbon? a) Carbon forms an interstitial solid solution in iron and Fe-C bonds are very strong. b) Carbon forms an interstitial solid solution in iron and the C atoms bind dislocations. c) Carbon forms a substitutional solid solution in iron and Fe-C bonds are very strong. d) Carbon forms a substitutional solid solution in iron and the C atoms bind dislocations. e) Carbon is the base element for diamond, which is very hard.
