Researchers at the University of Toronto have used an AI-driven active learning platform to identify six new metal alloys that retain strength under extreme heat and pressure, with potential applications in jet engines and nuclear power plants. The work, published in the journal npj Advanced Manufacturing<\/em> on June 23, 2026, was led by Canada Research Chair Yu Zou and first author Ajay Talbot in the university’s Department of Materials Science and Engineering.<\/p>\n

The system operates as a self-driving laboratory. The AI selects promising metal combinations, directs robots to manufacture and test them, and feeds the results back into the model to guide the next round of experiments. By using robotics and machine learning, the team compressed years of traditional materials discovery into weeks. The process is also compatible with laser-based additive manufacturing (3D printing), enabling the production of complex components that cannot be made using conventional methods.<\/p>\n

How does the self-driving laboratory work?<\/h2>\n

Most machine learning models require large datasets to make accurate predictions, and such data often does not exist for unexplored material combinations. To overcome this, the team used data-lean models that strategically select only a few samples to manufacture and test, then incorporate the experimental results back into the model to inform the next iteration. This approach, known as active learning, couples computer modeling, machine learning and robot-assisted manufacturing in a closed loop.<\/p>\n

“The way we get around that challenge is to use data-lean models that essentially feel their own way along,” Talbot explained. “Our active learning model strategically selects a few samples to manufacture and test, and the data from those experiments is fed back into the model to inform where we go next. It really speeds things up.”<\/p>\n

According to the study, the researchers identified six new printable alloys that are up to roughly 40% harder than the popular equiatomic NiCoCr at room temperature. The team focused on compositionally complex alloys made from nickel, cobalt and chromium, known as NiCoCr alloys.<\/p>\n

What did the new alloys achieve in testing?<\/h2>\n

Two of the six new alloys showed standout performance in the study, each targeting a different part of an engine. According to the published paper, Ni12<\/sub>Co62<\/sub>Cr26<\/sub> retains about 50% higher hardness than equiatomic NiCoCr at 600 \u00b0C (about 1,112 F), conditions found in the front section of a jet engine. In lab tests, it outperformed Inconel 625, an industry-standard nickel-based alloy made from more than 10 elements, by 4.5% in hardness.<\/p>\n

A second alloy, Ni36<\/sub>Co14<\/sub>Cr50<\/sub>, was designed for hotter sections of jet engines reaching 1,000 \u00b0C (about 1,832 F). The study reports that it reduces oxidation mass gain by 85% compared with conventional superalloys such as Inconel 625, meaning it resists being burned away at extreme temperatures. The researchers said they are aiming to ramp up to even higher temperatures, up to 2,192 F, in future work.<\/p>\n

Why do these alloys matter for jet engines and nuclear power?<\/h2>\n

“There’s enormous demand for materials that can stand up to huge swings of temperature and pressure, such as what you would find inside a jet engine or in the steam generators inside nuclear power plants, anywhere conventional steel just can’t survive,” Zou, the study’s corresponding author, said.<\/p>\n

Historical precedents show that material breakthroughs often reshape entire sectors. The development of superalloys in the mid-20th century enabled jet engines to operate at higher temperatures, transforming aviation. The new NiCoCr alloys are also compatible with 3D printing, opening pathways to components that are lighter, stronger and more resistant to the punishing conditions inside engines and reactors.<\/p>\n

What are the next steps for the research?<\/h2>\n

The researchers view the current results as an early demonstration of what the platform can achieve. “This nickel-cobalt-chrome system has just three elements in it,” Talbot noted. “But it’s great for showing that this whole closed-loop discovery platform really works. What we want to do next is ramp up the complexity a bit more to make even crazier stuff, with maybe up to 10 or 12 different elements.”<\/p>\n

The project was supported by the Natural Sciences and Engineering Research Council of Canada (NSERC), the Canadian Foundation for Innovation, the Digital Research Alliance of Canada, and the University of Toronto’s Acceleration Consortium, which receives funding from the Canada First Research Excellence Fund (CFREF).

FAQ<\/h2>\n

Who discovered the six new metal alloys?<\/h3>\n

Researchers at the University of Toronto’s Department of Materials Science and Engineering, led by Canada Research Chair Yu Zou and first author Ajay Talbot, identified six new metal alloys using an AI-driven active learning platform. The findings were published in npj Advanced Manufacturing<\/em> on June 23, 2026.<\/p>\n

How do the new alloys compare with Inconel 625?<\/h3>\n

One alloy of 12% nickel, 62% cobalt and 26% chromium demonstrated 4.5% higher hardness than Inconel 625 at temperatures up to 1,112 F. Another alloy of 36% nickel, 14% cobalt and 50% chromium showed 85% better oxidation resistance than Inconel 625 at temperatures reaching 1,832 F, according to the published study.<\/p>\n

How does the AI system find new alloys?<\/h3>\n

The system uses active learning, in which the AI selects promising metal combinations, directs robots to manufacture and test them, and feeds the experimental results back into the model to guide the next round of experiments. The researchers say this data-lean approach allows them to discover new alloys in weeks rather than years, and the alloys are compatible with 3D metal printing.<\/p>\n
