Question

Below is a unit cell for a hypothetical metal. The three inter-axial angles alpha, beta, and gamma are each 90 degrees (p. 54). All atoms are identical; their positions are identified with the letters A, B, C, and so on. Atom H is located at the center of the unit cell. What would this crystal structure be called? Neatly prepare a sketch that identifies the slip plane (011) and the Miller indices of the four slip directions in that plane. The shear strength of the (011) plane is tau c = 100 psi. A single crystal of this material is loaded in uniaxial tension with a stress of sigma along the [001] direction. Consequently, plastic deformation occurs on the (011) plane in the [111] direction. Clearly sketch the unit cell to show the angles phi and lambda from Figure 7.7 on page 205. Calculate those angles from your sketch. How high must a become to start plastic deformation on the (011) plane in the [111] direction?
