Application of neutron diffraction to the in situ study of thermal stability through measurements of creep evolution: (a) creep strain (%) and elastic microstrain (ppm) evolution at selected hkl planes at 250 °C under ascending cyclic loading for Al alloy marked as New below; (b) calculated stress exponents of the tested alloys at 200 °C and 250 °C. Alloys: A380: Al9.5Si−3.4Cu, Base: Al−7.1Si−1Cu−0.5Mg, New: Al−7Si−0.9Cu−0.5Mg−0.56Zr−0.20Ti−0.32V (wt.%) [50].
