摘要

本文描述了通过激光粉末床熔合(LPBF)生产高质量的垂直提升应用镁产品的能力所进行的工作。发展的一个重要步骤是为LPBF选择具有足够涂抹性的金属粉末。为了生产出低孔隙率、低粗糙度的零件,需要优化工艺参数。采用了一种有效的优化方法,通过分析一次构建作业中一系列薄壁和砌块样品来选择工艺参数。选择工艺参数后,制作基准件,对镁件打印设计准则进行评价。基于垂直举升应用的代表性轻质组件,成功生产了演示部件。在熔池和晶粒尺度上发现了非常细小的均匀组织。零件从底板上取下后,由于残余应力产生了一些变形。

Development of Magnesium Laser Powder Bed Fusion to Manufacture Light-weight Components for Vertical Lift Applications
This paper describes the work that was conducted to demonstrate the capability to produce high quality representative magnesium products for vertical lift applications by Laser Powder Bed Fusion (LPBF). An important step in the development was the selection of a metal powder with adequate spreadability for LPBF. Optimum process parameters are required for the production of parts featuring low porosity and low roughness. An efficient optimization approach was applied that enabled the selection of process parameters by analysis of an array of thin wall and block samples from one single build job. After the process parameter selection, benchmark parts were produced for evaluating design rules to print magnesium parts. Demonstrator parts were successfully produced based on a representative light-weight component for Vertical Lift application. A very fine homogeneous microstructure was found at the melt-pool and grain scale. After the removal of the parts from the baseplate, some deformation occurred due to residual stresses.
