Metals with a body-centered cubic (bcc) crystal structure are the basis of an important group of structural metals in engineering applications, such as ferritic steels and many refractory alloys. The ...

A Lawrence Livermore National Laboratory scientist and collaborators have demonstrated the first-ever "defect microscope" that can track how populations of defects deep inside macroscopic materials ...

In this section we shall investigate the dynamics of particles in a medium with a screw dislocation along the z direction as shown in Fig. 1. Before going to the details, let us briefly discuss the ...

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 ...

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 materials. So, as a ...
