that the first abruption of load-displacement curve in nanoindentation of Fe single crystal can be attributed to the first transition from elastic to plastic deformation characterized by the dislocation emission. Key words: initial plasticity; nanoindentation; multiscale simulation; dislocation  ......
in traditional BCC metals deformed via dislocation slip. Recovery involves individual dislocation motions within the existing grains whereas recrystallization involves movements of grain boundaries that eliminate... TNTZO alloy. Dislocation boundaries are formed normally to the primary slip planes and dislocation-free regions are separated from one another by dislocation boundaries. Fig.2 TEM images of cold......

STRUCTURE AND FORMATION MECHANISM OF DISLOCATION NETWORKS IN TiAl+Qu Xuanhui; Huang Baiyun(Powder Metallurgy Research Institute, Central South University of Technology, Changsha, 410083, China)Abstract:The structure and characteristics of dislocation networks in Ti50 Al ordered alloy deformed at room temperature were studied by means of TEM diffraction contrast analysis technique. The results......
of temperature, thus bonding strength of phase interfaces would be a little improved so that these actuated slip systems and movable dislocation cannot move and piled up ahead the phase interfaces... Fig.6 Dislocation configuration and slip modes during IP-TMF testing: (a) and (b) IP, Δεmech/2=0.75%; (c) and (d) IP, Δεmech/2=0.5% During TMF tests by IP loading, slip mode transformed from......
channels at low temperatures. The dislocation microstructure is inhomogeneous due to the formation of dislocation concentrations with high-density tangling at intermediate temperatures. The networks deposited at the γ/γ′ interfaces prevent dislocations from entering the γ′ precipitates at high temperatures. Key words: single crystal; Ni-base superalloy; tensile; microstructure; dislocation CLC......
