In the present study, Cu-25 wt %Sn alloy samples were prepared by the mechanical alloying process using planetary high-energy ball mill. The alloy formation and different physical properties associated with their formations were investigated as a function of milling times of 0, 10, 20, 70, 80, 100, 120, 150 and 200 h by means of the x-ray diffraction (XRD) technique, scanning electron microscopy (SEM) and differential scanning calorimeter (DSC). After milling time of 80 h, the complete formation of martensite transformation is observed. When milling time increases from 70 to 120 h, the grain size decreases from 20.8 to 8.6 nm, while the strain increases from 4.73 % to 7.59 %. It is inferred that the martensite volume fraction increases from 30 to 55 % when milling time increases from 20 to 200 h. Moreover, by using SEM the grain morphologies at different formation stages during ball milling are observed.
