: 冷强力旋压;Ti153;塑性变形; 中图分类号: TG30 收稿日期:1999-09-20 Effects of plastic deformation inhomogeneity on process of cold power spinning of Ti-15-3 Abstract: The effects of plastic deformation inhomogeneity on spinnability and forming quality of Ti 15 3 during the process of cold power spinning were studied. The results show that the inhomogeneity of plastic......

On the nucleation... Effect of large cold deformation after solution treatment on precipitation characteristic and deformation strengthening of 2024 and 7A04 aluminum alloys NING Ai-lin(宁爱林)1, 2, LIU Zhi-yi(刘志义)1......
Inhomogeneity and anisotropy of microstructure and mechanical properties in severe plastic deformation processed pure copper KANG Feng(康 锋)1, WANG Jing-tao(王经涛)1, DU Zhong-ze(杜忠泽)2 School... developed severe plastic deformation (SPD) techniques, which induces high plastic strains in bulk materials by uniform simple shear, thus ultra-fine grains can be obtained and the properties can......
mechanism; Zr alloy; EBSD; crystal plasticity; plastic deformation 1 Introduction Zr alloys are widely used in nuclear reactors because of their excellent mechanical properties, good corrosion resistance...). Their investigations focused on twinning, but they clearly failed to reproduce the plastic anisotropy and the deformed texture. To model the deformation of Zircaloy-4 at 500 °C, HONNIBAL et al [17] used the same CRSS......
Corrosion behavior of hypereutectic Al-23%Si alloy (AC9A) processed by severe plastic deformation JIANG Jing-hua(江静华)1, MA Ai-bin(马爱斌)1, SONG Dan(宋 丹)1, N. SAITO2, YUAN Yu-chun(袁玉春)1... study[15] indicated that the impact toughness of Al-23%Si (mass fraction) alloy after severe plastic deformation(SPD) by using an equal channel angular pressing with a rotary-die (RD-ECAP......
hardening caused by the tangled dislocation. Key words: zirconium alloy; dynamic compression; plastic deformation 1 Introduction Zirconium alloy as the fuel cladding material has been widely used... strain, the severe plastic deformation leads to the grain boundary difficult to distinguish, indicating that high density dislocations are piled up at the grain boundary. Under the different strain levels......
