为了研究激光增材制造高温合金的静态再结晶行为及其对力学性能的影响。以固溶强化型镍基高温合金GH3536为研究对象,采用激光选区熔化(SLM)制备试块和试棒,对其在1175 ℃进行不同时间的固溶处理,基于EBSD分析研究其在热处理过程中的静态再结晶行为,探讨其对拉伸性能的影响。结果表明:沉积态组织以沿建造方向生长的柱状晶为主,具有〈001〉丝织构。1175 ℃保温1 h的再结晶分数为61.8%,孪晶是再结晶形核的主要方式,再结晶程度随着保温时间的延长逐渐提高。根据Avirami方程拟合得到再结晶动力学曲线,与实验结果匹配良好。静态再结晶可以显著减弱力学性能的各向异性。保温时间超过1 h之后,力学性能变化幅度较小。 |

To study the static recrystallization behavior of laser additive manufacturing superalloys and their effect on mechanical properties, the solid-solution strengthened nickel-based superalloy GH3536 was investigated. The selective laser melting(SLM)method was used to prepare test blocks and bars, which were subjected to solution treatment at 1175 ℃ for different time. The static recrystallization behavior during heat treatment was investigated by EBSD analysis to explore its influence on the tensile properties. The results show that the as-built state organization is dominated by columnar grain growing along the build direction with〈 001〉 fiber texture. The recrystallization fraction after heating at 1175 ℃ for 1 h is 61.8%. Twinning is the main formation of recrystallization nucleation, and the degree of recrystallization gradually increases with the extension of the heating time. The recrystallization kinetic curve was obtained by fitting the Avirami equation, which matched the experimental results well. Static recrystallization significantly suppresses the anisotropy of the mechanical properties. The change magnitude of mechanical properties is small after the heating times more than 1 h. |
