Abstract
A Cu matrix composite with 5Â vol% TiB2 particles produced by powder metallurgy was subjected to equal channel angular pressing (ECAP) for 4 passes at 513Â K to enhance the strength of the Cu matrix through grain refinement. The introduction of TiB2 particles with the particle spacing comparable with particle size increased the effective strain and led to homogeneous deformation structure with low recrystallization nucleation propensity. The combination of high effective strain and low recrystallization nucleation driving force ensures continuous refinement of Cu matrix in the TiB2/Cu composite during the ECAP process. The mechanical behavior of the composite was discussed in terms of the microstructure evolution of Cu matrix during ECAP at elevated temperatures.
