• Zero-field ^<59>Co NMR, X-ray diffraction (XRD) and magnetization measurements have been made to investigate the mechanical alloying (MA) of ferromagnetic Co_<75>C_<25> powder as a function of milling time (MT). The MA in Co_<75>C_<25> proceeds rapidly with increasing MT up to 30h and more gradually above 30h by both the processes of dissolving C in the Co matrix and forming a metastable phase of Co_3C. XRD patterns show that the sample is in an amorphous state for MT≥50h, and its amorphization proceeds with further increasing the milling time. NMR results show that there coexist a saturated solid solution formed by dissolving C in Co, Co_3C and hcp-Co in the amorphous state and suggest that these phases consist of fine particles. The MA is not completed even for a long milling time of 100h.
