【摘要】 高温合金材料是制备飞机发动机叶片的材料,是推动国家航空航天发展的关键。国内高温合金发展存在瓶颈,然而国外高温合金数据保密性高,高温合金信息获取相对困难。国内高温合金数据的收集工作起步晚,且大部分关键数据都保存在企业中,不对外公开,导致开放共享的高温合金数据库较少,一定程度上制约了我国高温合金的研究。本数据集基于1980–2016年期间国际高温合金大会会议的论文集(International Symposium on Superalloys),采用人工阅读、像素点数值转化的方法,记录材料牌号与名称、材料成分、原材料信息、性能信息、实验条件等数据,从数据来源、数据审核人和数据误差率3个方面对数据质量进行控制和评价。并且,来自同一篇文章的数据拥有唯一的DOI标识。本数据集的研制对实现材料数据的知识产权保护与共享、对我国高温合金的发展都将起促进作用,同时满足了数据驱动的材料设计这一新型研究方式的需求。更多还原

【Abstract】 Superalloy is a crucial material for the development of aerospace industries. However, Due to high confidentiality imposed on superalloy data exchange abroad, acquisition of superalloy data has been relatively difficult. Domestic collection of superalloy data starts much later than and the databases are often not for open access, which to some extent restricts the development of superalloy research. Based on the International Symposium on Superalloys from 1980 to 2016, this study collects such information as materials grade and brand name, chemical composition, raw materials information, performance, processing and characterization conditions, by means of manual recording and pixel value conversion. Data quality is controlled and evaluated based on an examination of data source, data auditor and data error. And the data from the same article have a unique digital object identifier(DOI). Our building of this dataset is conducive to materials data sharing, intellectual property protection, and the development of nickel base superalloys in China, and it significantly meets the requirement of data-driven materials design.更多还原
