The question of whether microscopic line defects such as dislocations can exist in amorphous metals is discussed. The discussion is divided into three parts. The first part is a general consideration of the existence, detection, identification, stability, and motion of dislocations. The second part summarizes the experimental indications including the shear band characteristics, shear step distribution, and reverse shear behavior. The third part reports the computer simulations on the stability and the motion of dislocations in a Lennard-Jones amorphous solid. The conclusion is that such dislocations may exist in amorphous solids but their characteristics remain to be identified.
