Constant structure creep aluminium and two its solid solutions. Part II.

Popis výsledku v původním jazyce

Creep behaviour of pure aluminium and two of its solid solutions, i.e., AL-13.7 Zn and Al 5-5.5 Mg, were investigated extensively using constant structure creep experiments performed in the steady state creep stage. Results of the investigations of purealuminium are summarized in this second part of the paper. An analysis of the constant structure creep has shown that the creep rate is composed of two contributions resulting from different dislocation machanisms acting simultaneously in the course of the steady state creep. On of these mechanisms is dominant over the whole interval of experimental conditions. However, the ratio of these two contributions changes with experimental conditions of the creep test, i.e., the applied stress and temperature.Some characteristics of both mechanisms were determined. Both mechanisms are probably controlled by diffusion along high diffusivity paths, most probably diffusion along dislocation cores. However, the activation areas of these mechanisms
