| 英文摘要 | In this paper, bulk W-1 wt.% Y2O3-1 wt.% Ti (WYT) alloys with nanocrystalline (NC), ultrafine-grained (UFG), and fine-grained (FG) structures are fabricated using high-energy ball milling, spark plasma sintering and controlled annealing treatments. A systematic examination focuses on thermal load induced damages, particularly crack formation and mode, after repetitive thermal bombardments. The 1500 degrees C annealed WYT with UFG structure shows optimal thermal shock resistance, with only microcracks (similar to 0.29 mu m width) after thermal bombardments at an absorbed power density (APD) of 0.33 GW/m(2). In contrast, both the NC-WYT and 1700 degree celsius annealed WYT with FG structure demonstrate significant cracking with intergranular fracture at an APD of 0.22 GW/m(2), exacerbating with increasing the APD. By examining intrinsic microstructures, thermal conductivity, and mechanical properties, the potential mechanisms underlying the distinct thermal shock resistance of these alloys have been discussed. This work provides valuable insights into the thermal shock resistance of oxide-dispersion-strengthened W alloys with different microstructures. |
