The structure of four Fe-30Al alloys with different contents of Zr has been studied. Light optical microscopy (LOM), scanning electron microscopy (SEM) with EDX module, measurement of microhardness as well as X-ray diffraction (XRD) was used to determine the structure and phase composition. Addition of Zr to Fe-30Al leads, in the cast state, to the formation of a Fe-Al matrix with a hard lamellar eutectic skeleton. The eutectic is composed of thin lamellae of lambda(1)-Laves phase Zr(Fe,Al)(2) and Fe-Al (B2/D0(3)). Annealing at 1000 degrees C for 200 h results in the formation of the equilibrium phase tau(1) Zr(Fe,Al)(12). The presence of these phases in the matrix leads to increase of high temperature yield stress and strength. (C) 2011 Elsevier Ltd. All rights reserved.
