Why the slip of 1/2〈3 3 1] dislocations on {0 1 3) in C11b behaves differently at low and high temperatures?
چکیده انگلیسی
The 1/2〈3 3 1] dislocations in the tetragonal C11b structure of disilicides may possess a threefold non-planar core structure inherited from the BCC lattice. Due to non-metallic bonding, the dislocation splitting is intrinsically asymmetrical what has large consequences for dislocation properties. The 1/2〈3 3 1] slip on the {0 1 3) planes was observed at high temperatures above 900 °C when compressed along [0 0 1], but surprisingly, also below 500 °C when compressed along [0 15 1]. Why different dislocation behaviour is observed at high and low temperatures is explained in this paper.
