Solution 1

Make two left joins on TransferDetail with DepartmentUser one for the key TransferByFrom and 2nd for the key TransferByTo

As below

SQL

select  TID, TransferByFrom=frm.fname, TransferByTo=To.Fname,Date
from TransferDetail TD 
Left Join  DepartmentUser frm On TD.TransferByFrom=frm.DUID
Left Join  DepartmentUser To On TD.TransferByTo=To.DUID
