INTERACTIONS BETWEEN La2O3 PARTICLES AND DISLOCATIONS IN Mo-La2O3 ALLOYS M.L. Zhou1,J.X. Zhang1,Y.Q. Liu1,T.Y. Zuo1,D.M. Liu1 (1.The Key Laboratory of Advanced Functional Materials, Ministry... and the interaction between La2O3 particles with dislocations in MoLa2O3 wires were observed by SEM and TEM. It is shown that Mo-La2O3 wires possess much higher tensile strength than the pure Mo. In wires......
Internal friction peak associated with dislocations in Mg-0.6%Zr alloyShuwei LIU,Xiaofeng HU,Haichang JIANG,Xiuyan LI and Lijian RONG Institute of Metal Research,Chinese Academy of Sciences,Shenyang... to be caused by the creation and expansion of dislocations during plastic deformation.The P 2 peak is a thermally activated relaxation IF peak,and activation energy is 1.46 eV,which is caused......
account of the microstructure inhomogeneity, was used to investigate the micro-bending of metallic crystalline foils. In this model, both statistically stored dislocations (SSDs) and geometrically necessary dislocations (GNDs) are taken as the internal state variables. The strain gradient hardening in micro-bending of single-grained metal foils was predicted by evolution of GNDs. The predicted......
circuits were explained quantitatively. The present study has a general implication for the determination of the Burgers vectors of secondary interfacial dislocations in other systems.关键词:......
