Extended Data Fig. 3: Atom probe analysis of Al3Zr dispersoids in peak-aged Al–Zn–Mg–Cu samples.
From: Hydrogen trapping and embrittlement in high-strength Al alloys

a, D-charged. b, Uncharged sample prepared by PFIB. c, Uncharged samples prepared by electropolishing. Associated H peaks in the mass-to-charge ratio within the local Al3Zr dispersoids (middle) and composition analysis across the Al3Zr dispersoids (right) are also shown for each condition.
