      abstract     = {We recently reported that the columnar grain width of
                      Cr2AlC MAX phase coatings increases during oxidation (4 h
                      at 1120°C) by $80\%,$ while for 0.7 $at.\%$ Si additions to
                      Cr2AlC, coarsening of only $12\%$ was observed. Here, we use
                      nm scale compositional and microstructural investigations to
                      identify significant differences between Cr2AlC and
                      Cr2Al(Si)C. In particular, needle-shaped precipitates
                      coarsen into globular Cr3Si precipitates upon oxidation in
                      the Si-containing MAX phase. We infer that the presence of
                      these precipitates, which are located predominantly along
                      grain boundaries in the MAX phase, retards coarsening during
                      oxidation by Zener pinning.},
