激光粉末床熔合镍高温合金625工件的原位热成像

本文档提供了实验和相关测量文件的详细信息，可在数据集“具有各种悬垂和支撑的镍高温合金625工件激光粉末床熔化过程中的原位热成像”中下载。这些测量是在使用商用激光粉末床熔合(LPBF)系统制造小型镍高温合金625 (IN625)工件期间获得的。人工制品由两个半拱形特征组成，突出部分的坡度越来越大。这些悬垂的范围从垂直5°到垂直85°，增量为10°。工件的几何形状和加工过程是受控的，以确保沿悬垂几何形状加工的一致性。这种控制可以将悬挑几何形状和支撑结构的影响与层间扫描策略变化的影响隔离开来。测量包括每层的高速热成像，从中计算辐射温度、冷却速率和熔池长度。

期刊介绍： The Journal of Research of the National Institute of Standards and Technology is the flagship publication of the National Institute of Standards and Technology. It has been published under various titles and forms since 1904, with its roots as Scientific Papers issued as the Bulletin of the Bureau of Standards. In 1928, the Scientific Papers were combined with Technologic Papers, which reported results of investigations of material and methods of testing. This new publication was titled the Bureau of Standards Journal of Research. The Journal of Research of NIST reports NIST research and development in metrology and related fields of physical science, engineering, applied mathematics, statistics, biotechnology, information technology.
