Thermal Stability of Surface Layer Microstructures of Commercially Pure Titanium Treated by High Energy Shot Peening ZHANG Yu-juan1,REN Rui-ming1,CHEN Chun-huan1 (1.Dalian Jiaotong University, Dalian 116028, China) 摘要:Commercially pure titanium was treated by high energy shot peening, and annealed at a series of temperatures. The surface layers are characterized by means of scan electronic......
with increasing fluoride concentration can be related to the increasing ionic strength whereby gallium ions have to compete for anionic surfactant with other ions, such as Na ions, in solution. The high...J. Cent. South Univ. (2017) 24: 789-795 DOI: 10.1007/s11771-017-3481-1 Selective separation of gallium from aluminum in SDS–Ga–Al and SDS–Ga–Al–fluoride systems by ion flotation Bahri Zahra1, Rezai......

). However, many recent results show that DRX may take place in high pure Al under certain conditions. The stacking fault energe is not the only decided element of dynamic restoration. As for high pure... usually occurs in metals with low stacking fault energy or high pure aluminum [4]. 2) Continuous dynamic recrystallization(CDRX), which is proceeded by the progressive accumulation of dislocations......

sites and crack growth stages in both samples. Key words: Al7075 alloy; fatigue; transient liquid phase; gallium 1 Introduction Al7075-T6 alloy has low density and high specific strength, as well...) diffusion bonding using liquid gallium interlayer was investigated. The fatigue specimen was jointed at 460 °C under 10 MPa pressure for 10 min. The TLP bonded samples were homogenized at 465 °C for 2 h......
