Introduction

Cu-Fe based alloys are of interest in practical development of high strength, high electrical conductive Cu rich alloys and age-hardened Fe rich alloys. The Cu-Fe-Ni is an important system for producing composite materials with high electrical and thermal conductivity and low thermal expansion. The combination of these properties makes the Cu-Fe-Ni an interesting candidate for the development of new data storage facilities [2006Dan]. Moreover Cu-Fe-Ni alloys present attractive hard magnetic properties. Their high conductivity provides the necessary flexibility to fabricate soft magnets [2007Mon].
