| 英文摘要 | The effect of boron addition (0.010, 0.015, and 0.020 wt.%) on the microstructure and mechanical properties of an additively manufactured superalloy was examined. The as-built microstructure was investigated by scanning electron microscopy and transmission electron microscopy. The results demonstrate that boron precipitates as M3B2 boride at the grain boundary. The increase in boron content increases the amount of gamma/gamma ' eutectic and the size and fraction of M3B2 boride. Boron creates nanoscale fine borides at grain boundaries, which significantly reinforces grain boundaries. The mechanical property analysis indicated that the addition of boron improved the tensile ductility at 760 degrees C and stress rupture properties at 760 degrees C/780 MPa. However, with the excessive addition of boron, the mechanical property was reduced. |
