Characterization and properties of Al88Ce6TM6 amorphous alloys

Jianqi Zhang

Al88Ce6TM6 (TM = Ti, Cr, Mn, Fe, Co, Ni and Cu) amorphous alloys were manufactured by melt-spun technique. The evolution of crystallization, microstructure, mechanical and electrochemical properties of the alloys was investigated by DSC, XRD, TEM, micro-indentation and electrochemical techniques. The compositional dependence of the transition metals (TM) on glass-forming ability and thermal stability was studied in terms of various criteria. The research in the field of metallic glasses started since the discovery of ability to amorphize Au75Si25 in 1960 by means by rapid solidification, the amorphous alloys and Bulk Metallic Glassy alloys (BMG) may be distinguished on the basis of cooling rates and the thermal response as the material is heated above room temperature
