Mechanical alloying of Cu/Al plates and preparation of bulk amorphous/nanocrystalline composite by thermoplastic deformation

Xu Hongxia,Duan Huiping,Song Honghai(School of Materials Science and Engineering,Beijing University of Aeronautics and Astronautics,Beijing 100191,China)  
Strong thermoplastic deformation of overlapped Cu and Al plates had been realized by stir friction processing.Transmission electron microscopy investigation on the microstructure of the stirred zone demonstrate that the Cu and Al plates are torn into shreds and well-mixed in the stirred zone.The inter-diffusion between Cu and Al shreds happens,resulting in the mechanical alloying of Cu/Al plates.There are many amorphous phases with size of more than 1 micron and amorphous/nanocrystalline composite phases in the deformation zone.The average size of the nanocrystallines surrounded by amorphous phases,is about 5 nanometers.Experimental results strongly suggest that the thermoplastic deformation technique can not only be used to do mechanical alloying for bulk metallic materials but also to fabricate bulk amorphous/crystalline materials.
