The Fe(71)Si(15)Ti(10)Cu(4) ultrafine composite exhibits a favorable microstructural evolution and improved mechanical properties, i.e., large plastic strain of similar to 5% and pronounced work hardening characteristics. The mechanical properties of the ultrafine eutectic composite are strongly linked to the length scale heterogeneity and the distribution of the constituent phases. (C) 2010 Elsevier B.V.
