Effect of thermally induced relaxation on passivity and corrosion of an amorphous Al-Co-Ce alloy

► Corrosion behavior of amorphous, relaxed, and partially devitrified Al-Co-Ce alloys. ► Best corrosion behavior seen in relaxed condition. ► EXAFS characterization performed on alloys. ► Relaxed condition had shorter bond length, higher coordination number than as-quenched amorphous.
