High-speed photos shine a light on how metals fail

How things deform and break is important for engineers, as it helps them choose and design what materials they're going to use for building things. Researchers at Aalto University and Tampere University have stretched metal ...

Geologists simulate deep earthquakes in the laboratory

More than 20 years ago, geologist Harry Green, now a distinguished professor of the graduate division at the University of California, Riverside, and colleagues discovered a high-pressure failure mechanism that they proposed ...

Are amorphous solids elastic or plastic?

In a crystalline solid, the atoms form an ordered lattice. Crystalline solids respond elastically to small deformations: When the applied strain is removed, the macroscopic stress, as well as the microscopic configuration ...

Rejuvenating metallic glass to prevent fracturing

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 ...

Researchers fabricate high-quality transparent ceramic

Mid-infrared lasers have been widely used in imaging, detection, diagnostics, environmental monitoring, medicine, industry, defense and others. For mid-infrared laser systems, low phonon energy gain materials are key factors.

Research team proposes technology for producing superplastic wire

Currently, low-alloy aluminum is widely used in electrical engineering and machine building. At the same time, it should be noted that modern electrical engineering places very high and in some cases mutually exclusive requirements ...
