X射线微计算机断层扫描（microCT）可用于分析增材制造中使用的粉末原料。在本文中，我们展示了这种分析方法的专用工作流程，特别是通常用于商业粉末床熔融（PBF）增材制造（AM）系统的Ti6Al4V粉末。提出的方法包括样本量要求，扫描条件和设置，重建和图像分析程序。我们设想这种方法将支持增材制造社区中粉末分析的标准化。这是为了通过识别粉末中的杂质和缺陷，最终提高增材制造零件的质量。用于增材制造的金属粉末的MicroCT分析方法描述了简化技术使用的标准工作流程样品要求和图像分析工作流程描述（C）2018作者。由爱思唯尔公司出版
X-ray micro computed tomography (microCT) can be applied to analyse powder feedstock used in additive manufacturing. In this paper, we demonstrate a dedicated workflow for this analysis method, specifically for Ti6Al4V powder typically used in commercial powder bed fusion (PBF) additive manufacturing (AM) systems. The methodology presented includes sample size requirements, scan conditions and settings, reconstruction and image analysis procedures. We envisage this method will support standardization in powder analysis in the additive manufacturing community. This is aimed at ultimately improving the quality of additively manufactured parts, through the identification of impurities and defects in powders.MicroCT analysis of metal powders for additive manufacturingMethod describes a standard workflow simplifying usage of the techniqueSample requirements and image analysis workflow is described (C) 2018 The Author(s).
