Micro-Plasticity in Beryllium Bronze

摘要

The dynamic relaxation spectrum of beryllium bronze for a broad temperature interval 20-650 ℃ is investigated in order to determine the micro-plastic behavior of the material at levels of relative deformation at the range of 10~(-4)-10~(-2). The properties of beryllium bronze are determined by the higher concentration of the structural defects and the lower binding force between the defects and the dislocation lines. Upon deformation with amplitude higher than the critical one, separation of the dislocation lines from the alloying elements takes place.
