Abstract Phase transformation of Co has been studied by using high temperature X-ray diffraction.At a temperature above 425℃ the hcp structure of Co transformed to an fcc phase. The most finding is that the transformation below 425℃ is very difficult to induce by simple cooling. If fcc-Co deformed by grinding,it is easy to transform into hcp phase at room temperature.So, at the process of transformation from fec into hcp, deformation is very important.

Key words: Co phase transformation X-Ray diffraction
