摘要

The strengthening of aluminum alloy 6061 (AA6061) by different point defects was determined experimentally using a shock wave technique. Decay of the amplitude of elastic precursor wave tau(el) with propagation distance h was studied in four groups of AA6061 samples, namely, that in the super-saturated solid solution state (SSSS), and those strengthened by atomic clusters (short-range order), by Guinier-Preston zones I and by Guinier-Preston zones II after, respectively 7.5, 240 and 960 min aging of the SSSS samples at 145 degrees C. The dependences tau(el)(h) were found to be kinked at stress tau*, corresponding to the transition of the control of dislocation motion from phonon viscous drag at tau(el) tau* to thermally activated obstacle passage at tau(el) tau*. The values of strengthening by atomic clusters, GP-I, and GP-II zones were found equal to tau(sro) = 67, r(GP-I) = 67, and tau(GP-II) = 124 MPa, respectively. Activation volumes corresponding to the interaction of dislocations with the studied defects, estimated based on tau(el) tau* segments of the measured dependences tau(el) (h), were found to be in reasonable agreement with existing concepts of dislocation/defect interactions.
