The Microstructural Studies of Ag/Ni20 Fibre Composites Processed by Severe Plastic Deformation

Abstract:

Article Preview

In present work, Ag/Ni20 fibre composites were prepared by coating extrusion, bunched extrusion, and severe plastic deformation. The microstructure and its evolving rules were investigated by SEM and TEM, and the evolving mechanism of microstructures were also analyzed and discussed. The results showed that: (1) Ni fibre, the enhancement phase of Ag/Ni20 fibre composites, would refine, fracture, and nodularize leading to the mix structure of short fibre and particles duing severe plastic deformation; (2) the (111) of Ag and (111) of Ni could misfit with each other by dislocations and forms half-coherent interface.
