In the temperature range of 6 to 300 K an effect of the high amplitude ultrasound waves on amplitudedependences of decrement and modulus defects in the antimony and bismuth single crystals of different orientation is studied. The character of changes of the decrement and modulus defect amplitude dependences under the influence of the high amplitude ultrasound indicates that dislocation multiplication, obstacle break‐through by dislocation pile‐ups or deformation twinning may be observed in crystals depending on the ultrasound propagation direction and the temperature interval investigated.
