Abstract:
A method for manufacturing a ductile particle-reinforced amorphous matrix composite in which ductile metallic particles are dispersed in an amorphous matrix, said method comprising steps of:preparing a mixture consisting of amorphous powder and 0.1-40 vol % of ductile metallic powder uniformly dispersed therein having a flow stress lower than that of the amorphous powder during fabrication in a super-cooled liquid region of the amorphous powder; obtaining a billet by compacting said mixture in a hermetically sealing condition; and plastic working the billet at a temperature in the super-cooled liquid region of the amorphous powder to obtain the ductile particle-reinforced amorphous matrix composite in which ductile metallic particles are dispersed in the amorphous matrix.
