The tool, DuctGPT, combines advanced <a class=\"word_1777063122735\" href=\"https:\/\/www.energy.gov\/science\/doe-explainsartificial-intelligence\" rel=\"nofollow noopener\" target=\"_blank\">AI<\/a> with physics-based modeling to help researchers predict materials with the appropriate properties to function in the extreme conditions inside of fusion reactors. The challenge is to rapidly explore a wide range of potential alloy compositions that can maintain high-temperature strength, while retaining the ductility necessary for manufacturing the materials.<\/p>\n<p>The project, led by Ames Lab Scientist Prashant Singh, was designed to demonstrate how physics-based <a class=\"word_1777063122735\" href=\"https:\/\/www.energy.gov\/science\/doe-explainsartificial-intelligence\" rel=\"nofollow noopener\" target=\"_blank\">AI<\/a> tools can accelerate materials discovery for fusion energy systems, particularly for materials capable of handling intense heat, radiation, and mechanical stress.<\/p>\n<p>The team began with an existing <a class=\"word_1777063122735\" href=\"https:\/\/www.energy.gov\/science\/doe-explainsartificial-intelligence\" rel=\"nofollow noopener\" target=\"_blank\">AI<\/a> model called AtomGPT, which was developed by the National Institute of Standards and Technology. They modified and fine-tuned the model with existing material science data.<\/p>\n<p>DuctGPT can search through a very large number of element combinations in seconds. Additionally, researchers can pose their questions and define parameters in conversational text, which is an integral aspect of GPT (generative pre-trained transformer) <a class=\"word_1777063122735\" href=\"https:\/\/www.energy.gov\/science\/doe-explainsartificial-intelligence\" rel=\"nofollow noopener\" target=\"_blank\">AI<\/a> programs.<\/p>\n<p>\u00a0\u201cNow when you ask it, \u2018I want to design a material for fusion that has all x, y, z properties that are critical for use in fusion reactors. Tell me the combination of elements which satisfy the criteria,\u2019 it will give you those combinations of elements with properties,\u201d said Singh.<\/p>\n<p>Tungsten is a material of specific interest. It is considered one of the best materials for withstanding very high heat, such as the heat generated during nuclear fusion. It also has a relatively short cooling period and remains radioactive for the shortest amount of time after being exposed to nuclear fusion. Unfortunately, it also has a major drawback.<\/p>\n<p>\u201cTungsten\u2019s main limitation is its lack of low-temperature tensile ductility, which makes it difficult to form into complex shapes,\u201d said Singh. \u201cWith DuctGPT, we can now query compositions within a desired space, such as tungsten-titanium-zirconium-hafnium, to identify alloys that maintain tungsten\u2019s strength and high melting temperature while improving ductility.\u201d<\/p>\n<p>Material queries can be performed on a normal desktop computer, rather than needing costly supercomputer calculations. As a result, DuctGPT can reduce discovery time from months to days or hours.\u00a0<\/p>\n<p>\u201cAmes Lab has demonstrated that ductile refractory alloys can be predictively designed,\u201d Singh said. \u201cWe have unique capabilities to synthesize and test the predicted materials, confirming that they truly exhibit the competing properties required for fusion applications.\u201d<\/p>\n<p>The team is expanding the platform to better predict how materials behave during operation by integrating new data and models.
