Experimental Study of the Interaction between Recrystallization and Precipitation Processes of an AA8011 Commercial Alloy

<table>Thermograms of 85-DHS samples. (a) Effect of the heating rate for samples pre-heated for 20 minutes at 300°C (same notation as Figure <a href="../fig7/">7</a>). (b) 20 min preheating at different temperatures measured at 5°C/min. ▴ without preheating. <svg height="9.4750004" id="M122" style="vertical-align:-0.273pt" version="1.1" viewbox="0 0 10.1 9.4750004" width="10.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
