Notes:
A Cu-TiB2 composite was successfully fabricated by in-situ liquid mixing process, and itsmicrostructure, mechanical properties as well as electrical conductivity were evaluated. ForCu-2vol.%TiB2 composite, the hardness was as high as 5GPa and the Young’s modulus was 130GPa.And hardness and Young’s modulus of Cu-6vol.%TiB2 composite was 5.6Gpa and 138GPa,respectively. With the increase of the TiB2 content, hardness and Young’s modulus ofCu-10vol.%TiB2 composite were 20 and 12%, respectively, which was higher than that ofCu-2vol.%TiB2 composite. Young’s modulus of the Cu-TiB2 composite in this paper was in goodagreement with the prediction by Hashin-Shtrikman (H-S) model. Furthermore, the electricalconductivity of the Cu-TiB2 composite showed its maximum value of about 78%IACS and decreasedwith the increase of the TiB2
