Asymmetrical stress field results in _________ strengthening in comparison to non-symmetrical stress field.

Asymmetrical stress field results in _________ strengthening in comparison to non-symmetrical stress field. Correct Answer Less

A solute atom possesses non-symmetrical stress field when the lattice distortion is not equal in all directions. This stress field is developed due to defects. This type of stress field gives a higher degree of strengthening.
