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.
