A Strengthening Model of Cu-Cr In-situ Fibrous Composites Produced by Equal Channel Angular Pressing

摘要：

　　The composite filament structure was produced in the Cu-5.7%Cr and Cu-12.4%Cr as-cast alloy ingots by using equal channel angular pressing (ECAP) at room temperature.Optical and TEM microstructure,micro-hardness,tensile strength and electrical conductivity of ECAPed samples were investigated.The rotation and spreading of Cr particles took place during ECAP,and resulted in long thin in-situ filaments.The tensile strength increased with the number of the ECAP passes.A strengthening model was recommended to predict the enhancement of the tensile strength in Cu-Cr in situ fibrous composites.
