You can export .dat to .stl and .obj formats.
As far as I know, Inventor can import .stp - so you would only need conversion from .obj/.stl to .stp, which probably is possible as well.
However those exports will likely be just meshes, not the native type of volumetric models you would expect in professional CAD software, so expect a lot of issues (if it works at all).
