；残余应力；疲劳性能Microstructure and fatigue properties of Ti-6Al-4V titanium alloy treated by wet shot peening of ceramic beadsCHEN Guo-qing1, TIAN Tang-yong1, ZHANG Xin-hua2, LI Zhi-qiang2, ZHOU Wen-long1(1...:Ti-6Al-4V alloy was treated by the wet shot peening using ceramic beads. The results demonstrate that after the wet shot peening the surface hardness increases from 330HV to 416HV. The surface......
of shot peening and electropolishing, the changes of the fatigue behavior of the alloy exposed at 700 ℃ in air for 10000 h was studied. The results show that the fatigue strength of electropolishing specimens is higher than that of shot peening specimens before exposure. The fatigue strengths of the alloys with both surface conditions reduce after long-term thermal exposure......

Trans. Nonferrous Met. Soc. China 27(2017) 1956-1963 Prediction model for surface layer microhardness of processed TC17 via high energy shot peening Li-xing SUN, Miao-quan LI, Hui-min LI School... shot peening (HESP) at the air pressures ranging from 0.35 to 0.55 MPa and processing durations ranging from 15 to 60 min. The microhardness (HV0.02) from topmost surface to matrix of the HESP processed......
-enhanced deposition (IBED). The composition distribution, bonding strength, hardness and the wear resistance of the film were investigated. Shot peening was introduced to post treat the modified... and high bonding strength. Thus the hardness, wear resistance and fretting fatigue resistance of Ti 811 alloy are increased remarkably. Compared with shot peening treatment or ion-beam-enhanced deposition......
