1) cyclic deformation
Tensile behaviors of ultrafine grained copper (UFG-Cu) processed by equal channel angular pressing (ECAP) were investigated at room temperature in the as-processed state and after cyclic deformation treatment.
A study has been performed relating to the micromechanisms of cyclic deformation in polycrystalline copper and aluminium under low cycle impact fatigue (LCIF) loading.
It was shown that the appearance ofDBs seems to be a general phenomenon in difFerently oriented crystals during cyclic deformation.
2) cyclic deformation
Numerical relationship between hardness and microstructure of JLF-1 steel after cyclic deformation
To investigate the microstructural stability,stress-strain response and fatigue fracture of a new generation γ-TiAl alloy with high Nb content under cyclic deformation,Low aycle fatigue tests under total strain controlling were carried out in the temperature range of 550℃～750℃ Deformed microstructures and fatigue fracture surfaces were observed.
The monotonic tensile and uniaxial cyclic deformation behaviors of the SiC_p/6061A1 alloy composites were simulated numerically by using elastic-plastic finite element code ABAQUS, and the simulated results were compared with the corresponding experiments in order to discuss the reasonability of the finite element simulation.
4) circular deformation behavior
The result shows that, the circular deformation behavior of two-phase steel not only relates to the evolutional process of the dislocation configuration of the microstructure, but also is affected by the intensity, type and loading modes of the circular load.
