The Motion of Dislocation in Iron Pinning by Carbon Interstitials
The dislocation 1/2(1-10) in iron is constructed. The motion behaviors of dislocation 1/2(1-10) in iron, as well as the dislocation with the Carbon located in dislocation core, are simulated by the molecular dynamics method with a modified analytic embedded atomic method (MAEAM). The carbon atoms are easy captured by the dislocation core and they can block the dislocation moving. After the carbon atoms are separated from the dislocation, the moving velocities of the dislocation are similar as the case of single dislocation.
