Mechanical performance dataset for alloy with applications at low temperatures

Area of Science:

• Materials Science
• Mechanical Engineering
• Low-Temperature Physics

Background:

• Advanced technologies like liquid fuels, superconductivity, and quantum technology necessitate materials with exceptional strength and toughness at cryogenic temperatures.
• Steel, aluminum, and titanium alloys are commonly used, but emerging medium- and high-entropy alloys show superior low-temperature mechanical properties.
• A need exists for validated data sources to accelerate research and development in these demanding applications.

Purpose of the Study:

• To curate and provide a comprehensive, open-access dataset of metallic alloys for cryogenic applications.
• To facilitate data-driven research in material screening, design, and discovery for low-temperature environments.
• To establish a standardized format for material properties and metadata.

Main Methods:

• Automated data extraction from literature using machine learning and natural language processing.
• Supplementation of automated extraction with manual inspection and correction for enhanced data quality.
• Curation of key performance parameters (yield strength, tensile strength, elongation, impact energy) and metadata (composition, processing, testing conditions).

Main Results:

• A comprehensive dataset of low-temperature metallic alloys has been successfully curated and made publicly available.
• The dataset includes critical mechanical properties and detailed metadata in a standardized format.
• The data extraction workflow demonstrated high efficiency and quality through a combination of automated and manual processes.

Conclusions:

• The curated dataset provides a valuable resource for researchers and developers working with materials at cryogenic temperatures.
• This open repository will accelerate the discovery and design of novel alloys for demanding technological applications.
• The standardized data format promotes reproducibility and facilitates collaborative research in materials science.
