The slip in FCC crystal occurs in the (111) plane in {110} direction, but generally it is not energetically favourable, so it slips into two partial dislocations. The correct partial dislocation is represented by which of the following equation? |
| A. | a<sub>o</sub>/2[1 1 0] a<sub>o</sub>/3[-1 2 1]+a<sub>o</sub>/2[112] |
| B. | a<sub>o</sub>/2[1 1 0] a<sub>o</sub>/6[-1 2 1]+a<sub>o</sub>/6[112] |
| C. | a<sub>o</sub>/2[1 1 0] a<sub>o</sub>/6[2 -1 -1]+a<sub>o</sub>/2[11-2] |
| D. | a<sub>o</sub>[1 1 0] a<sub>o</sub>/3[-1 2 1]+a<sub>o</sub>/2[112] |
| Answer» D. a<sub>o</sub>[1 1 0] a<sub>o</sub>/3[-1 2 1]+a<sub>o</sub>/2[112] | |
