In the framework of simplified anisotropic first strain gradient elasticity, the necessary material parameters are computed for cubic materials including aluminum (Al), copper (Cu), iron (Fe) and tungsten (W) using a second nearest-neighbour modified embedded-atom-method interatomic potential. The ...
Section III discusses isolated dislocation in a strained layer. Section IV analyzes the driving force in more complex situations.doi:10.1016/S0065-2156(08)70173-XL.B. FreundAdvances in Applied MechanicsL. B. Freund. The mechanics of dislocation in strained-layer semiconduc- tor materials. Adv. ...
materials contain metallic bonds to accommodate the strain of dislocations, showing a different scenario with the oxide ceramics35. Meanwhile, we show that the ultra-dense dislocations show an extra toughening effect through interaction with the cracks. The strain field of dislocations in the high-...

Typically these materials (occasionally referred to as compositionally complex alloys) contain two or three phases. The simultaneous presence of topological order and chemical disorder involving numerous elements is unique in metals. It discriminates HEAs from metallic glasses and conventional crystals and ...

In materials science, dislocations are irregularities within the crystal structure or atomic scale of engineering materials, such as metals, semi-conductors, polymers, and composites. Discussing this specific aspect of materials science and engineering, Introduction to Dislocations is a key resource for ...
