 note = {0000-0003-1397-9556, Oxide Dispersion Strengthened Cu alloy (ODS-Cu) with Y2O3 has great application potential in the field of fusion. In the previous fabrication method by adding metal Y as the source of Y2O3, severe sticking occurred during mechanical alloying (MA) and huge Y particles still remained after MA. Considering that Cu-Y compounds are more brittle than pure Y, which is expected to resolve the sticking issue, and have lower Y enrichment, which will make it easier to form uniform Y distribution, ODS-Cu with various content of Y by adding Cu2Y or Cu6Y were fabricated through MA and Hot isostatic pressing (HIP) process. A comparative analysis was made for the samples with addition of Cu2Y and Cu6Y. The results showed that, compared with Cu2Y, Cu6Y is easier to form uniform Y distribution. The most likely reason is that the Cu6Y is more brittle and less Y abundance than Cu2Y. The sample with 0.39 wt% Y with Cu6Y addition has the highest Vickers hardness, possibly because of solution strengthening caused by higher content of interstitial O, and better electrical conductivity than the sample with 1.19 wt% Y with Cu6Y possibly because of the more uniform formation of Y2O3 and the absence of precipitation phases.},
