The authors regret that the numbers on the abscissa in Fig. 13 were incorrectly labeled. As a result, the threshold stress values reported were inaccurate in the abstract and Section 3.6. The corrected Fig. 13 is displayed below. The threshold stresses for alloy Q2 are 9.2 and 9 MPa for the peak- and over-aged conditions, respectively, whereas the threshold stresses for alloy Q1 are 9 MPa for the peak-aged specimen and 10 MPa for the over-aged one. These corrections do not affect the conclusions reached as a result of this research. The authors would like to apologize for any inconvenience caused. [Figure presented] Fig. 13. Creep properties of alloys Q1 and Q2 under compressive stresses at 400 °C for peak-aged (350 °C/16h + 400 °C/12 h) or over-aged (350 °C/16h + 450 °C/24 h) conditions. Creep data of a similar alloy (Al-0.01Er-0.05Sc-0.06Zr-0.03Si) was also plotted for comparison purposes .
