Experimental evidences indicate that a same final product of bcc alpha -Fe solid solution is formed upon milling for all samples. During the transformation, the XRD peaks of alpha -Fe phase shift to lower diffraction angles, and those of borides disappear in turn, first the metastable Fe//3B and Fe//2//3B//6 and then the stable Fe//2B.
