| 摘 要： | The effects of yttrium and cerium on the compression properties of Ni_3Al-base alloys have beeninvestigated.The results reveal that the addition of about 0.1 wt% Y to Ni_3Al-B alloy is effective for improvingthe ductility at 1100℃.A ductility increase of about 100% is observed for this Y doped alloy.The yttrium re-fines grains of the alloy.An YNi_5 phase is found to be precipitated on the grain boundaries in the alloy con-taining 0.3 wt% Yor more.Adding about 0.1 wt% Ce to Ni_3Al-B-Cr-Zr alloy obviously improves the ductilityof the alloy at 1100℃.A ductility increase of about 50% is obtained for this alloy.The added cerium also pre-vents the formation of γ+γ' eutectic and refines it.The bulk phase of CeNi_4 appeares at the front of the eutecticin the alloys containing 0.1 wt% Ce or more.
