We study the effects of neutron captures in AGB stars on \oq Fe-group\cqbelements, with an emphasis on Cr, Fe, and Ni. These elements show anomalies in$^{54}$Cr, $^{58}$Fe, and $^{64}$Ni in solar-system materials, which arecommonly attributed to SNe. However, as large fractions of the interstellarmedium (ISM) were reprocessed in AGB stars, these elements were reprocessed,too. We calculate the effects of such reprocessing on Cr, Fe, and Ni through1.5\msb and 3\msb AGB models, adopting solar and 1/3 solar metallicities. Allcases produce excesses of $^{54}$Cr, $^{58}$Fe, and $^{64}$Ni, while the otherisotopes are little altered; hence, the observations may be explained by AGBprocessing. The results are robust and not dependent on the detailed initialisotopic composition. Consequences for other \oq Fe group\cqb elements are thenexplored. They include $^{50}$Ti excesses, and some production of$^{46,47,49}$Ti. In many circumstellar condensates, Ti quantitatively reflectsthese effects of AGB neutron captures. Scatter in the data results from smallvariations (granularity) in the isotopic composition of the local ISM. For Si,the main effects are instead due to variations in the local ISM from differentSNe sources. The problem of Ca is discussed, particularly with regard to$^{48}$Ca. The measured data are usually represented assuming terrestrialvalues for $^{42}$Ca/$^{44}$Ca. Materials processed in AGB stars or sourceswith variable initial $^{42}$Ca/$^{44}$Ca ratios can give apparent $^{48}$Caexcesses/deficiencies, attributed to SNe. The broader issue of GalacticChemical Evolution is also discussed in view of the isotopic granularity in theISM. \end{abstract}
