Abstract
Due to a lower symmetry of the tetragonal C11b structure when compared with the cubic BCC lattice, the 1/2[331] dislocation cores are split asymmetrically contrary to the 1/2[111]; BCC dislocations. This has essential impact on their behaviour and, consequently, on mechanical properties. Various types of dislocation dissociations are analyzed in the frame of anisotropic elasticity with the help of the data from ab initio calculations of gamma-surfaces for generalized stacking faults in intermetallic compound MoSi2.
Abstract (in Czech)
Ve struktuře C11b jsou jádra dislokací typu 1/2[331] rozštěpeny asymetricky. To má podstatný vliv na jejich chování a zvláště na mechanické vlastnosti. S využitím ab initio výsledků pro gamma-plochy pro zobecněné vrstevné chyby analyzujeme v rámci anizotropní elasticity různá rozštěpení jader dislokací v intermetalické sloučenině MoSi2.
