| 中文摘要: |
| 采用电子束焊接技术对铂基合金与GH3128进行焊接。利用工业CT、扫描电子显微镜、显微硬度仪和材料万能试验机，研究了铂基合金与GH3128焊接接头显微组织、力学性能及断口形貌。结果表明:铂基合金与GH3128具有良好的焊接性能，焊接接头的质量良好，无缺陷，成分均一，焊缝区显微硬度在360~380之间，焊缝强度为499 MPa，断裂方式为韧性断裂，断裂位置位于铂基合金一侧。 |
| 英文摘要: |
| The platinum base alloy and GH3128 were welded by electron beam welding technology. The microstructure, mechanical properties and fracture morphology of the platinum based alloy and GH3128 welded joints were studied by industrial CT, scanning electron microscope, microhardness tester and material universal testing machine. The results showed that the platinum based alloy and GH3128 have good welding performance. The welding joint has good quality, no defect, uniform composition, the micro hardness (HV) of weld zone was between 360 to 380, weld strength was 499 MPa, fracture mode as ductile fracture and fracture position on one side of platinum base alloy. |
