A team of researchers from the Chinese Academy of Sciences and the University of Cambridge has found a way to rejuvenate metallic glass to prevent it from fracturing. In their paper published in the journal Nature, the group ...
Metals with nanoscale crystal grains are super-strong although they do not retain their structure at higher temperatures. As a result, it is challenging to explore their high strength during materials applications. In a new ...
Researchers at Tampere University of Technology and Aalto University taught machine learning algorithms to predict how materials stretch. This new application of machine learning opens new opportunities in physics and possible ...
