Deformation of an Al-7Mg alloy with extensive structural micro-segregations during dynamic plastic deformation
Jin, Shenbao; Tao, Nairong; Marthinsen, Knut; Li, Yanjun (Journal article; Peer reviewed, 2015)The microstructure evolution and deformation behavior of an as-cast Al–7Mg alloy with severe Mg segregation zones distributed on grain boundaries and in interdendrite regions subjected to dynamic plastic deformation (DPD) ... -
Effects of atom probe analysis parameters on composition measurement of precipitates in an Al-Mg-Si-Cu alloy
Jin, Shenbao; Su, Haokai; Qian, Feng; Li, Yanjun; Sha, Gang (Peer reviewed; Journal article, 2022)Defining analysis parameter space for reliable composition measurement of materials is of significance for atom probe tomography applications. This research carefully explores the influence of specimen temperature and ... -
Enhanced dispersoid precipitation and dispersion strengthening in an Al alloy by microalloying with Cd
Qian, Feng; Jin, Shenbao; Sha, Gang; Li, Yanjun (Journal article; Peer reviewed, 2018)The dispersion hardening effect of Mn(Fe)-containing dispersoids in aluminium alloys has long been ignored since it is difficult to achieve a high number density of fine dispersoids with conventional alloying compositions. ... -
Enhanced nucleation and precipitation hardening in Al-Mg-Si(-Cu) alloys with minor Cd additions
Qian, Feng; Zhao, Dongdong; Mørtsell, Eva Anne; Jin, Shenbao; Marioara, Calin Daniel; Andersen, Sigmund Jarle; Sha, Gang; Li, Yanjun (Peer reviewed; Journal article, 2020)This work reports a novel effect of impurity element Cd on enhancing the precipitation kinetics and increasing the peak hardness of Al–Mg–Si(–Cu) alloys during artificial ageing. It is found that the number density of age ... -
Formation of incoherent deformation twin boundaries in a coarse-grained Al-7Mg alloy
Jin, Shenbao; Zhang, Kai; Bjørge, Ruben; Tao, NR; Marthinsen, Knut; Lu, K; Li, Yanjun (Journal article; Peer reviewed, 2015)Deformation twinning has rarely been observed in coarse grained Al and its alloys except under some extreme conditions such as ultrahigh deformation strain or strain rates. Here, we report that a significant amount of Σ3 ... -
Formation of {11-21} twin boundaries in titanium by kinking mechanism through accumulative dislocation slip
Jin, Shenbao; Marthinsen, Knut; Li, Yanjun (Journal article; Peer reviewed, 2016)The twinning behavior and kinking behavior of a commercial purity Ti subjected to room temperature dynamic plastic deformation (DPD) has been studied. Three types of deformation twins, {1012}, {1122} and {1121}, have been ... -
Formation of Σ3{110} incoherent twin boundaries through geometrically necessary boundaries in an Al-8Zn alloy subjected to one pass of equal channel angular pressing
Jia, Hailong; Jin, Shenbao; Li, Yanjun (Journal article, 2018)For coarse grained (CG) alloys with high stacking fault energies (SFEs), like aluminum, deformation twins can rarely form. Here, we report that Σ3{110} incoherent twin boundaries (ITBs) could be generated in a CG Al-8Zn ... -
Prominent role of multi-scale microstructural heterogeneities on superplastic deformation of a high solid solution Al–7Mg alloy
Zha, Min; Zhang, Hongmin; Jia, Hailong; Gao, Yipeng; Jin, Shenbao; Sha, Gang; Bjørge, Ruben; Mathiesen, Ragnvald; Roven, Hans Jørgen; Wang, Hui-Yuan; Li, Yanjun (Peer reviewed; Journal article, 2021)Achieving high superplasticity in single-phase Al alloys remains a challenge, since the fine-grained structure required for superplastic deformation coarsens rapidly in the absence of dispersed second-phase particles during ... -
Synergistic effects of Cd, Si and Cr additions on precipitation strengthening and thermal stability of dispersoids in AA3003 alloy
Qian, Feng; Jin, Shenbao; Wan, Di; Cheng, X; Sha, Gang; Li, Yanjun (Peer reviewed; Journal article, 2022)The thermally stable Mn-rich dispersoids in Al alloys were recently reported to have a significant dispersion strengthening effect. Further improvements in the dispersion strengthening and thermal stability of Mn-rich ...
