Data for: Probing the structure and mechanical properties of the graphite nodules in ductile cast irons via nano-indentation

Each text file contains the load vs penetration data for a single nano-indentation test. See article "Probing the structure and mechanical properties of the graphite nodules in ductile cast irons via nano-indentation" for additional details.每个文本文件均包含单次纳米压痕（nano-indentation）测试的载荷-压入深度数据。更多详细信息可参阅论文《通过纳米压痕探究球墨铸铁中石墨球的结构与力学性能》（Probing the structure and mechanical properties of the graphite nodules in ductile cast irons via nano-indentation）。
