*2.3. Heat Treatments*

Heat treatments of both the initial homogenized (IS) and the HPT-processed samples were performed over different time periods and at different temperatures between 50 ◦C and 240 ◦C in a silicon oil bath with a thermal stability of ±0.5 ◦C. After the heat treatments, the samples were quenched in RT-water to ensure fast cooling and high accuracy of heat treatment duration [34].
