An Investigation of the Microstructures and Mechanical Properties of FeSiBCuAl Alloys

Abstract

Fe76.5-xSi13.5B9Cu1Alxalloys were fabricated by arc melting method plus copper mould casting technique. The effects of Al content on the microstructures and mechanical properties of the alloys were investigated. The results showed that the Al content significantly affects the microstructures and mechanical properties of the alloys. The addition of Al element into the alloy results in a variation from nanostructures to coarse grained structures. At the same time, the hardness and elastic modulus decrease with increasing the Al content.
