摘要：
Fe-Al solid-solution alloys, with interstitial-free matrix to avoid detrimental kappa-carbides, have been investigated in the context of low-density steels for automotive applications. The mechanical properties of the 6.8 wt.% Al-containing alloy were found to be comparable to those of dual-phase steel but with the benefit of reduced density and better formability. Future work on these alloys should concentrate on improving the Young's modulus and the deep drawability. (C) 2012 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
