Exercise: 8. Checking l sin λ = constant

The results for the two stages of deformation are shown in the table.

Percent strain Sample length / mm λ (to nearest 5°) l sin λ / mm
40 25 30° 9.3
100 36 15° 12.5

To within experimental error, these results show that l sin λ = constant is also observed for the cadmium crystal.

Using the measurements from the deformed crystal, it is possible to calculate the initial orientation of the slip plane (φ0 and λ0).

End of exercise.
