摘要：
The effect of natural aging on the aging response of the AlMgSiCu alloy AA6111 was studied using low-temperature electrical resistivity measurements. Two experimental conditions were examined: (i) natural aging for 2 weeks followed by artificial aging in the temperature range of 120-200 degreesC and (ii) natural aging for variable periods followed by aging at 180 degreesC. The resistivity variation during underaging and overaging periods was discussed in relation to the microstructural evolution. (C) 2004 Elsevier B.V. All rights reserved.
