| 1 | Temperature-gradient induced microstructure evolution in heat-affected zone of electron beam welded Ti-6Al-4V titanium alloy显示文摘The heat-affected zone(HAZ) of electron beam welded(EBW) joint normally undergoes a unique heat-treating process consisting of rapid temperature rising and dropping stages, resulting in temperature-gradient in HAZ as a function of the distance to fusion zone(FZ). In the current work,microstructure, elements distribution and crystallographic orientation of three parts(near base material(BM) zone, mid-HAZ and near-FZ) in the HAZ of Ti-6Al-4V alloy were systematically investigated. The microstructure observation revealed that the microstructural variation from near-BM to near-FZ included the reduction of primary α(αp) grains, the increase of transformed β structure(βt) and the formation of various α structures. The rim-α, dendritic α and abnormal secondary α(αs) colonies formed in the mid-HAZ, while the 'ghost' structures grew in the near-FZ respectively. The electron probe microanalyzer(EPMA) and electron back-scattered diffraction(EBSD) technologies were employed to evaluate the elements diffusion and texture evolution during the unique thermal process of welding. The formation of the various α structures in the HAZ were discussed based on the EPMA and EBSD results. Finally, the nanoindentation hardness of 'ghost' structures was presented and compared with nearby βt regions. | Shilin Zhang Yingjie Ma Sensen Huang Sabry S.Youssef Min Qi Hao Wang Jianke Qiu Jiafeng Lei Rui Yang | 2019 | Journal of Materials Science & Technology2019，35，8： | 6 |
| 2 | Fatigue crack tip plastic zone ofα+βtitanium alloy with Widmanstatten microstructure显示文摘The recent studies had focused on the fatigue crack propagation behaviors of α+β titanium alloys with Widmanstatten microstructure. The fascinated interest of this type of microstructure is due to the superior fatigue crack propagation resistance and fracture toughness as compared to other microstructures,which was believed to be related to the fatigue crack tip plastic zone(CTPZ). In this study, the plastic deformation in fatigue CTPZ of Ti-6 A1-4 V titanium alloy with Widmanstatten microstructure was characterized by scanning electron microscope(SEM) and electron backscatter diffraction(EBSD). The results showed that large-scale slipping and deformation twinning were generated in fatigue CTPZ due to the crystallographic feature of the Widmanstatten microstructure. The activation of twinning was related to the rank of Schmid factor(SF) and the diversity of twin variants developing behaviors reflected the influence of SF rank. The sizes of CTPZ under different stress intensity factors(K) were examined by the white-light coherence method, and the results revealed that the range of the plastic zone is enlarged with the increasing K(or crack length), while the plastic strain decreased rapidly with the increasing distance from the crack surface. The large-scale slipping and deformation twinning in Widmannstatten microstructure remarkably expanded the range of fatigue CTPZ, which would lead to the obvious larger size of the observed CTPZ than that of the theoretically calculated size. | Yingjie Ma Sabry S.Youssef Xin Feng Hao Wang Sensen Huang Jianke Qiu Jiafeng Lei Rui Yang | 2018 | Journal of Materials Science & Technology2018，34，11： | 3 |

| 10 | Characterization ofα_(2)Precipitates in Ti–6Al and Ti–8Al Binary Alloys:A Comparative Investigation显示文摘Transmission electron microscopy(TEM)and atom probe tomography(APT)techniques were used to investigate the nanoscale orderedα_(2)(Ti_(3)Al)precipitates in Ti–Al binary alloys.Ti–6Al and Ti–8Al binary alloys were solution treated and aged to obtain Widmanstatten microstructure and promoteα_(2)precipitates.The TEM results displayed strong short-range ordering ofα_(2)precipitates in Ti–8Al alloy,while no evidence of the superlattice reflections ofα_(2)in Ti–6Al alloy.The results acquired from APT showed theα_(2)clusters and atoms distribution at the interface between the matrix andα_(2)precipitates.The size and morphology ofα_(2)particles in Ti–8Al alloy,respectively,obtained by TEM and APT are closely consistent.Meanwhile,the APT results displayed tiny size clusters in Ti–6Al alloy,which supposed to give evidence of the initial ordering process ofα_(2)precipitates in the absence of correlative results from TEM. | Sabry S.Youssef Xiaodong Zheng Yingjie Ma Sensen Huang Min Qi Jianke Qiu Ruixue Zhang Peitao Hua Shijian Zheng Jiafeng Lei Rui Yang | 2021 | Acta Metallurgica Sinica(English Letters)2021，34，5： | 1 |
