Episode 1: High-strength alloys created using thermally stable nanoparticles

In this podcast episode, MRS Bulletin’s Laura Leay interviews Tao Yang from the City University of Hong Kong in China who focuses on the innovative design of advanced structural materials. In the area of high-strength alloys, Yang’s research team looked specifically at how to stabilize nanoparticles at high temperatures. In an alloy of Ni59.9-xCoxFe13-Cr15Al6Ti6B0.1, Yang’s team achieved ultra-stable nanoparticles at 800–1000°C. They achieved this effect by tailoring the concentration of cobalt. While nanoparticles have already been seen to improve the strength of materials, Yang’s team has provided insight into how this can be achieved at high temperatures. This research is published in a recent issue of Nature Communications (https://doi.org/10.1038/s41467-022-32620-6).
