  • Dry ball milling and wet ball milling for fabricating

    Yttria-reinforced copper matrix composites were prepared by dry ball milling (DBM) and wet ball milling (WBM) respectively followed by spark plasma sintering (SPS). It is to determine which milling process is better for fabricating Cu–Y2O3 composites. It is found that Cu–Y2O3 composites synthesized by DBM exhibit better densification mechanical and electrical properties than those by WBM.
