Abstract
The crystalline matrix - bulk metallic glass (BMG) particle composites having two different matrix strengths were manufactured by electroless plating of copper and nickel on BMG powder and subsequent consolidation. The plastic behavior of composites was determined by the uniaxial compression test in the supercooled liquid region of BMG. The localization of the deformation in the soft matrix strongly lowers the flow stress in the composite containing a soft matrix; A homogenous deformation was obtained in the composite having the matrix strength close to the BMG strength. The strain state in the composites was interpreted by the finite element method simulation.
