Structure, properties and applications of thin Fe-Al layers

Reuther, H.
Fe-Al show interesting physical properties and offer some
special industrial applications. There are phase transitions combined with
changes in the magnetic behaviour. Another interesting fact is the excellent
oxidation and corrosion resistance of iron aluminides even at high temperatures.
Thin Fe-Al layers can be produced in different ways. Ion beam methods enable
to produce surface layers on bulk material modifying the initial properties
completely. The properties depend strongly on the phase structure induced
by the preparation process. 57-Fe Mössbauer spectroscopy, and in the
case of surface layers conversion electron Mössbauer spectroscopy
is very suitable to identify this phase structure. In the present work,
it is described for Al implanted Fe layers. Depending on implantation dose
and energy both magnetic and non-magnetic phases can be produced. Due to
the inhomogeneous distribution of Al in the Fe target a layer structure
of different phases can be created. Moreover, due to double implantation
an Fe-Si-Al alloy can be prepared
