Materials can deform plastically by atomic-scale line defects called dislocations. Many technical applications are based on this fundamental process, such as forging, but we also rely on the power of ...

AMES, Iowa – Materials engineers don’t like to see line defects in functional materials. The structural flaws along a one-dimensional line of atoms generally degrades performance of electrical ...

LIVERMORE, Calif. – Lab researchers have discovered that three is the magic number when it comes to strengthening metals. Since the Iron Age, metallurgists have known that metals such as steel become ...

Researchers show that Cartan's First Structure Equation links crystal defects to the same mathematical rules governing electric currents and magnetic fields. (Nanowerk News) A fundamental goal of ...

Atomic-level toughness mechanisms are essential for defense materials, impacting fracture resistance and performance under ...

Researchers have discovered that engineering one-dimensional line defects into certain materials can increase their electrical performance. Materials engineers don't like to see line defects in ...
