Machine learning could be key to producing stronger, less corrosive metals

8 Aug 2017 - It may not be as catchy as chains and weak links, but physicists and engineers know "a material is only as strong as its weakest grain boundary".

OK, that's not catchy at all, but here's the point: grain boundaries are a big deal. They are the microscopic, disordered regions where atom-sized building blocks bind the crystals - i.e. grains - together in materials.

More importantly, grain boundaries help determine the properties of metals important to humans. For example, they can influence a metal's strength (buildings), corrosion resistance (bridges) and conductivity (electricity).

But while researchers have studied grain boundaries for decades and gained some insight into the types of properties grain boundaries produce, no one has been able to nail down a universal system to predict if a certain configuration of atoms at grain boundaries will make a material stronger or more pliable.

Enter the interdisciplinary Brigham Young University research team of Conrad Rosenbrock, Eric Homer and Gus Hart. The Ph.D. student Conrad Rosenbrock and two professors - one engineer, Eric Homer, and one physicist, Gus Hart - might have cracked the code by juicing a computer with an algorithm that allows it to learn the elusive "why" behind the boundaries' qualities.

Their method, published in the most recent issue ofNaturejournal Computational Materials , provides a technique to produce a "dictionary" of the atomic building blocks found in metals, alloys, semiconductors and other materials. Their machine learning approach analyzes Big Data - think: massive data sets of grain boundaries - to provide insight into physical structures that are likely associated with specific mechanisms, processes and properties that would otherwise be difficult to identify.

"We're using machine learning, which means algorithms can see trends in lots and lots of data that a human can't see", Eric Homer stated. "With Big Data models you lose some precision, but we've found it still provides strong enough information to connect the dots between a boundary and a property."

When it comes to metals, the process can evaluate properties like strength, weight and lifespan of materials, leading to the eventual optimization of the best materials. Although the group is not actually creating materials yet, they can now decipher the "why" and the "how" of the make-up.

Researchers said their paper is the first to attempt to crack the code of the atomic structures that heavily influence grain boundary properties with the computer algorithms of machine learning.

"It's kind of like Siri; Siri works by taking sounds and turning them into vowels and consonants and ultimately words by accessing a massive Apple database", Gus Hart stated. "We're using the same concept. We have a large database, and our algorithm is taking grain boundaries and comparing it against that database to connect them to certain properties."

The end goal is to make it easier and more efficient to develop materials that can be combined to make strong, lightweight and corrosion-free metals. The researchers believe they are at the front end of what could be a 10 or even 20-year process to create innovative alloy structures that provide practical solutions to major structures.

"Our nation spends $500 billion a year on corrosion", Eric Homer stated. "If you can reduce the cost of treating corrosion even a few percent by developing more resistant metals, you can save billions every year. That's not a small amount of money."
