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 ... -
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 ...
