Figure 6
LA velocity of SBN40 vs. temperature after ZFC from 450 °C on first cooling to T W (curve 1), then aging for 10 h at (a) T W = 120 °C, (b) T W = 130 °C, and (c) T W = 135 °C and cooling down (curve 2) until it merges with a ZFC reference curve at T R, continuous reheating up to 150 °C (curve 3), and subsequent continuous cooling back to T R (curve 4). Red circle and blue triangle are reference curves measured on ZFH and ZFC, respectively without aging.
