Research topics from publications: Densification behavior, mechanical and electrical properties of in-situ TiB2p/Cu composite powder via vacuum hot pressing; A well-balanced strength and electrical conductivity in rolled composite prepared by in-situ TiB2p/Cu composite powder; Microstructure evolution and properties of multi-scale precipitate strengthened Cu-Cr-Nb alloy. Representative work: The TiB2p/Cu composites were prepared by current-assisted vacuum hot pressing (CAVHP) combined with rolling using in-situ spherical TiB2p/Cu composite powder as raw material. The effects of rolling deformation on the microstructure and properties of the sintered TiB2p/Cu composite were investigated. The results show that CAVHP leads to a rapid densification of the composite powder compact, and the subsequent rolling deformation is able to eliminate the unclosed pores and achieve a uniform distribution of TiB2p. The dynamic recrystallization during cold rolling refines the Cu matrix grains to ultrafine grains with an average grain size of 0.47 μm. The cold rolled TiB2p/Cu composite obtains a
