摘要：
Fe, Fe-Al2O3, and Fe-Pb nanocrystalline alloys were prepared using ball milling. Fe-Al2O3 forms a nanocomposite and rule-of-mixtures hardening occurs with an additional contribution due to grain size reduction during milling. Fe-Pb forms a non-equilibrium solid solution where hardening appears to be modulated by Ph clustering and segregation to grain boundaries. (c) 2006 Acta Materialia Inc. Published by Elsevier Ltd.
