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.
Meanwhile，the integrity and normalization of
data are significant for the utility of materials data. This work described
that a high-quality materials genome engineering superalloys database has been
built and accessible on line--https://www.mgedata.cn/. Through materials genome
engineering, superalloys big data can accelerate superalloys development. Based
on the International Symposium on Superalloys from 1980 to 2016, this work
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. However,
the different description ways bring not only about complexity, unevenness of
data and confusion in query, together with the intelligent property dispute to
impact adversely the data quality and to lead directly to the failure of data
mining when exploring the novel materials. To control and evaluate data quality
therefore is necessary based on an examination of data source, data auditor and
data error. And then, the data from the same article have a unique digital
object identifier (DOI). Finally, materials data standards drafted in our group
are demonstrated in this case, including the unified description and naming
method of digital object identifier for materials scientific data. And the
applications of the standards in superalloys data are discussed in
details. Our building of this
superalloys database 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.
