with spherical cavity (ECAEE-SC); numerical simulation; strain accumulation; grain refinement 1 Introduction With the rapid development of material science and technology, higher performance requirements have... on the geometrical parameters of the fabricated die (~1.05) proposed by IWAHASHI et al [22]. Thus, it is believed that ECAEE-SC process can be used as a novel SPD method for plastic strain accumulation......

, dislocations move and additional dislocations are gradually generated. Then, the resulted work hardening (or strain hardening) makes the metal harder and stronger due to the accumulation...Trans. Nonferrous Met. Soc. China 30(2020) 2090-2106 Strain anisotropy models for refined diffraction line profile analysis in cubic metals Xiang DAI1, Fu-lin JIANG1,2, Jin LIU1, Luo-yi WU1, Ding-fa......
J. Cent. South Univ. (2020) 27: 1666-1677 DOI: https://doi.org/10.1007/s11771-020-4398-7 Influence of radial forging process on strain inhomogeneity of hollow gear shaft using finite element method... orthogonal design method. To examine the strain inhomogeneity of the forging workpiece, the strain inhomogeneity factor was introduced. The results reveal that the maximum effective strain......
RECRYSTALLIZATION BEHAVIOR AND PRIOR AUSTENITE GRAIN BOUNDARY CORROSION IN THE PLANE STRAIN COMPRESSION CONDITION FOR A LOW CARBON X70 PIPELINE STEEL Y.Y.Shan1,Y.S.Li2,Y.H.Li3,J.Wang4 (1.Institute... pipeline steel was studied in the plane strain compression condition. It was found that the dynamic recovery but no dynamic recrystallization occurred in the current experimental condition. A method......
structure was designed, and experimental research was carried out. The results show that the direct extrusion and torsional compound deformation can significantly enhance the accumulation strain of deformed... of deformation process was investigated using finite element software. Effect of torsion angle on cumulative strain during the deformation process was studied, and the non-uniformity of the equivalent......
