1High Temperature Deformation Behavior of 4340 Steel: Activation Energy Calculation and Modeling of Flow Response显示文摘The 4340 steel is extensively utilized in several industries including automotive and aerospace for manufacturing a large number of structural components.Due to the importance of thermo-mechanical processing in the production of steels,the dynamic recrystallization(DRX)characteristics of 4340steel were investigated.Namely,hot compression tests on 4340steel have been performed in a temperature range of 900-1200℃and a strain rate range of 0.01-1s-1 and the strain of up to 0.9.The resulting flow stress curves show the occurrence of dynamic recrystallization.The flow stress values decrease with the increase of deformation temperature and the decrease of strain rate.The microstructure of 4340steel after deformation has been studied and it is suggested that the evolution of DRX grain structures can be accompanied by considerable migration of grain boundaries.The constitutive equations were developed to model the hot deformation behavior.Finally based on the classical stress-dislocation relations and the kinematics of the dynamic recrystallization;the flow stress constitutive equations for the dynamic recovery period and dynamic recrystallization period were derived for 4340steel,respectively.The validity of the model was demonstrated by demonstrating the experimental data with the numerical results with reasonable agreement.S V Sajadifar G G Yapici M Ketabchi B Bemanizadeh 2013Journal of Iron and Steel Research(International)2013,20,12:5
2Open reduction of a total talar dislocation: A case report and review of the literature显示文摘BACKGROUND Total talar dislocation (TTD) is very uncommon for many orthopedic surgeons and emergency/trauma specialists. Scarce cases of TTD have been reported, mainly in the form of open fracture-dislocation injury. CASE SUMMARY We report a very rare injury of closed TTD with a follow-up period of 36 mo. Initial closed reduction was not successful because of a fractured highly unstable medial malleolus displaced into the ankle mortise, blocking the relocation of the talus. The patient was able to walk pain-free after the 3rd month of surgery. At the 36-mo follow-up, there were 10 degrees of flexion loss and 10 degrees of extension loss in the tibiotalar joint. Furthermore, 5 degrees of subtalar joint inversion-eversion loss was present. CONCLUSION Open reduction should be performed for closed TTDs unless closed reduction is successful.Furkan Yapici Mehmet Coskun Muhammet Coskun Arslan Erman Ulu Yunus Emre Akman 2019World Journal of Clinical Cases2019,7,14:2
