Thermally Exposed and As-Built Additively Manufactured A625-GRCop42 Bimetallic Interface EPMA Data

GRCop-42 was additively manufactured using laser powder bed fusion, A625 was deposited directly onto GRCop-42 surface using powder-based directed energy deposition. A Cameca SX-100 electron microprobe was used to provide back scattered electron and composition mapping, initial spot composition (in GRCop-42, A625, and on the interface), and composition measurements on a line across the bimetallic interface. Samples in the data set include as-built samples and samples that underwent thermal exposure at 1500F (816C) for 50, 100, 200, and 500 hours.

GRCop-42 集成制造采用激光粉末床熔融技术，A625 材料直接沉积于 GRCop-42 表面，此过程基于粉末基定向能量沉积。Cameca SX-100 电子探针被应用于提供背散射电子和成分映射，以及 GRCop-42、A625 和界面处的初始点成分分析，以及对双金属界面线上的成分进行测量。数据集包含原始样品以及经 1500°F（816°C）热暴露 50、100、200 和 500 小时的样品。
