Abstract

Homogeneously tailored 30 vol.% Cu-base amorphous powder/Cu-base ductile crystalline alloy composites were successfully fabricated using the multi-extrusion process. The microstructural variation of composites occurring during the extrusion was investigated using both calculation and experiment as a function of the number of extrusions as well as the area reduction ratio. The composite shows a good interface between the amorphous and the crystalline phases. The strength was about 950 MPa and elongation was about 30%.
