J. Cent. South Univ. (2021) 28: 572-581 DOI: https://doi.org/10.1007/s11771-021-4622-0 Anchoring effect and energy-absorbing support mechanism of large deformation bolt ZHAO Tong-bin(赵同彬)1, 2, XING... and interfacial shear stress are analyzed. Additionally, the influence of structure element position on the anchoring effect of large deformation bolt is discussed. At last, the energy-absorbing support mechanism......

are calculated based on kinetics analysis of high temperature deformation, which are then used for deformation mechanism analysis combined with microstructure investigation. The results show that deformation mechanisms vary with deformation conditions: at low strain rate range, the deformation mechanism is mainly dislocation slip; at low temperature and high strain rate range, twinning is the main......
University, Zhengzhou 450002, China Received 23 September 2009; accepted 30 January 2010 Abstract: The mechanical properties and deformation mechanism of semi-continuously casting and as-extruded AZ70... is improved and even superplasticity exhibits. SEM and OM were used to clarify the deformation mechanism. It is suggested that dynamic recrystallization (DRX) is the coordination deformation mechanism......
