interparticle spacing, and volume fraction of the primary B2 precipitates in Fe-based
superalloys with varying Al concentration. The results are analyzed with a model
incorporating polydispersity and interference effects and verified by transmission electron
microscopy (TEM) characterizations. As the Al amount increases from 4 to 10 mass pct, there
is an approximately 40 pct decrease in the average interparticle spacing and~ 30 pct …
