Abstract

Increasing layer thickness in Laser Powder Bed Fusion (PBF-LB) process of metals enable increasing productivity and facilitate industrialisation of metal additive manufacturing (AM) process. Understanding of microstructure in as-built stage and possible post-processing steps to modify the microstructure is critical for metal AM components. Haynes 282 Nickel based superalloy, typically used in aerospace and energy industries, was manufactured using PBF-LB process at 60 microns layer thickness. Two different solution treatment temperatures were studied to analyse the recrystallization behaviour of the as-built material. The as built microstructure consisted high dislocation density given the rapid cooling in PBF-LB process. Solution treatment at 1150°C resulted in reduced dislocation density but similar morphology to grains in as built condition with visible residual melt pool boundaries. Solution treatment at 1250°C resulted in recrystallised grain structure. The recrystallisation behaviour is discussed with relation to manufacturing process and kinetic behaviour of alloying elements.

溶液处理温度对通过激光粉末床熔融技术制造的 Haynes 282 再结晶行为的影响
在金属激光粉末床熔融(PBF-LB)工艺中增加层厚可提高生产率,促进金属增材制造(AM)工艺的工业化。了解成型阶段的微观结构以及改变微观结构的可能后加工步骤对于金属增材制造部件至关重要。Haynes 282 镍基超耐热合金通常用于航空航天和能源行业,采用 PBF-LB 工艺制造,层厚 60 微米。研究了两种不同的固溶处理温度,以分析成型材料的再结晶行为。由于 PBF-LB 工艺冷却速度较快,坯料的微观结构具有较高的位错密度。在 1150°C 进行固溶处理后,位错密度降低,但形态与坯料状态下的晶粒相似,并具有明显的残余熔池边界。在 1250°C 下进行固溶处理会产生再结晶晶粒结构。讨论了再结晶行为与制造工艺和合金元素动力学行为的关系。
