FATIGUE STRENGTH DETERMINATION OF BUTT WELDED JOINTS BY FEM J.Brózda1,M.Szubryt1 (1.Instytut Spawalnictwa (Institute of Welding), ul. Bl. Czeslawa 16/18, 44-100 Gliwice, Poland) Abstract:The influence of welding parameters of butt joints, made by three processes (MMA, MAG and T.I.M.E), on their geometric characteristics has been evaluated, which in turn caused a change of the fatigue strength......

on the investigation of the tensile properties of spray formed ultra-high strength Al10.8Zn2.9Mg1.9Cu alloys, the high-cycle fatigue properties under different theoretical stress concentration factors were investigated, the fatigue fracture surfaces and microstructures were observed, and the fatigue mechanism was discussed. The results indicate that the ultimate tensile strength of spray formed Al10.8Zn2.9Mg1.9Cu......
The Effect of Shot Peening on the Fatigue Strength of Pure Titanium ZHANG Jian-bin1,YU Shu-rong1,FAN Ding1 (1.State Key Laboratory of Advanced Nonferrous Metal Materials, Lanzhou University... measurements in this paper. The results show that shot peening increased the fatigue strength of pure titanium. The substructures of shot peened pure titanium consist of dislocations, deformation twins......

is the most widely used, in the conventional peak-aged temper (T6), have the highest strength by far. The need for high strength coupled with good fatigue performance and stress corrosion cracking SCC..., and the over-aged temper (T7) improve the fatigue performance and SCC resistance. However, this results in loss of strength compared with the T6 temper[9-11]. In some cases, 7B04-T7451 is used after......
