crystal structure. Draw a unit cell of Al. Identify and draw a plane in the {100} family that is neither (100) nor (100). What is the planar density of this family of planes? Draw another unit cell of Al. Identify and draw a plane in the {101} family that is neither (101) nor (101). What is the planar density of this family of planes? Draw another unit cell of Al. Identify and draw a plane in the {111} family that is neither (111) nor (111). What is the planar density of this family of planes? Of the three planes you just drew, which one is close-packed? In this plane, what family of directions has the highest linear density? (The densest direction of the densest plane of a crystal structure form something called a slip system, which will be important when we talk about metal deformation in Chapter 7)

Question
1 Aluminum Slip System Identification Aluminum has a lattice parameter of 0.405 nm and a density of 2.71 g/cc at room temperature. (a) Based on this information, and taking into account the atomic weight, demonstrate that Al has an FCC crystal structure. (b) Draw a unit cell of Al. Identify and draw a plane in the {100} family that is neither (100) nor (100). What is the planar density of this family of planes? (c) Draw another unit cell of Al. Identify and draw a plane in the {101} family that is neither (101) nor (101). What is the planar density of this family of planes? (d) Draw another unit cell of Al. Identify and draw a plane in the {111} family that is neither (111) nor (111). What is the planar density of this family of planes? (e) of the three planes you just drew, which one is close-packed? In this plane, what family of directions has the highest linear density? (The densest direction of the densest plane of a crystal structure form something called a slip system, which will be important when we talk about metal deformation in Chapter 7.)
