  We have investigated the local atomic structure of amorphous TM-Ti alloys (TM
= Co, Ni, Cu) produced by Mechanical Alloying by means of EXAFS analyses on TM
and Ti K-edges. Coordination numbers and interatomic distances for the four
alloys where found and compared. EXAFS results obtained indicated a shortening
in the unlike pairs TM-Ti as the difference between $d$ electrons of TM and Ti
atoms increases, suggesting an increase in the chemical short range order
(CSRO) from TM = Co to Cu.
