Synthesis and properties of a Cu-Ti-TiB2 composite hardened by multiple mechanisms

► In situ formed TiB2 nanoparticles in copper matrix via argon atomization. ► Preparation of Cu-Ti-TiB2 composite by gas atomization and hot isostatic pressing. ► High hardening of the Cu-Ti-TiB2 composite due to development of modular structure, precipitation of Cu4Ti(m) and the presence of TiB2.
