Abstract:	The effect of natural aging on the aging response of the A1-Zn-Mg-Zr alloy AA7020 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 90-160 degrees C and (ii) natural aging for variable periods followed by aging at 160 degrees C. The resistivity variation during underaging and overaging periods was discussed in relation to the microstructural evolution. (C) 2007
