Angular distributions of sputtered Fe and W atoms from Fe-W alloy (25 wt%) under 27 keV Ar ion bombardment have been measured by Rutherford backscattering and a collector
on which the sputtered atoms with different ejection angle

is linked with the ejection angle
θ.
Comparing this work with our previous work on Cu-Au and Ti-Ni alloy systems implies that the mechanism of the preferential sputtering teems to associate with the mass ratio of components. A simple model has been used and it is found that the target surface topography may be an important factor to cause the variation of angular distribution of sputtered atoms.
