Building Data-driven Models with Microstructural Images: Generalization and Interpretability
This paper explores the use of convolutional neural networks for classifying microstructure.
3D Printing of High-Strength Aluminum Alloys
3D printing, or additive manufacturing, of metals uses a direct energy source, such as a laser or electron beam, to alloy powders, but has succeeded for only a few metals. Often, large columnar grains and cracks are generated during the solidification stage. In this paper, John Martin et al. confront this problem for aerospace-grade aluminium alloys […]
3D Printing of High-Strength Aluminium Alloys
Metal-based additive manufacturing, or three-dimensional (3D) printing, is a potentially disruptive technology across multiple industries, including the aerospace, biomedical and automotive industries. Building up metal components layer by layer increases design freedom and manufacturing flexibility, thereby enabling complex geometries, increased product customization and shorter time to market, while eliminating traditional economy-of-scale constraints. However, currently only […]
High-Dimensional Materials and Process Optimization using Data-driven Experimental Design with Well-Calibrated Uncertainty Estimates
The optimization of composition and processing to obtain materials that exhibit desirable characteristics has historically relied on a combination of scientist intuition, trial and error, and luck. We propose a methodology that can accelerate this process by fitting data-driven models to experimental data as it is collected to suggest which experiment should be performed next. […]
Robust FCC solute diffusion predictions from ab-initio machine learning methods
We evaluate the performance of four machine learning methods for modeling and predicting FCC solute diffusion barriers. More than 200 FCC solute diffusion barriers from previous density functional theory (DFT) calculations served as our dataset to train four machine learning methods: linear regression (LR), decision tree (DT), Gaussian kernel ridge regression (GKRR), and artificial neural […]
Industrial materials informatics: Analyzing large-scale data to solve applied problems in R&D, manufacturing, and supply chain
In this review, we discuss current and potential future applications for materials informatics in industry. We include in this discussion not only the traditional materials and chemical industries, but also other manufacturing-intensive sectors, which broadens the relevance of materials informatics to a large proportion of the economy. We describe several high-level use cases, drawing upon […]
High-Throughput Machine-Learning-Driven Synthesis of Full-Heusler Compounds
A machine-learning model has been trained to discover Heusler compounds, which are intermetallics exhibiting diverse physical properties attractive for applications in thermoelectric and spintronic materials. Improving these properties requires knowledge of crystal structures, which occur in three subtle variations (Heusler, inverse Heusler, and CsCl-type structures) that are difficult, and at times impossible, to distinguish by […]
Materials Data Infrastructure: A Case Study of the Citrination Platform to Examine Data Import, Storage, and Access
Considerations are presented around the design of a materials data infrastructure including import of structured and unstructured data, storage of that data for archival and retrieval, and access to that data through programmatic and graphical interfaces. In particular, the choices around technologies used in such an infrastructure, the benefits and drawbacks of those technologies, and […]
Role of materials data science and informatics in accelerated materials innovation
Building on these efforts, new tools are being developed to improve data curation, such as the Materials Data Curation System,70 Materials Commons,71 and the Citrine platform.55 Chance and Paul72 outline how to connect the wide variety of data sets and tools using a semantic web infrastructure. Kalidindi, S. R., Brough, D. B., Li, S., Cecen, A., […]
Beyond bulk single crystals: A data format for all materials structure–property–processing relationships
In this article, we discuss a hierarchical data structure used for storing materials data called the physical information file (PIF).
