Achieving dispersed fine soft Bi particles and grain refinement in a hypermonotectic Al-Bi alloy by severe plastic deformation and annealing
Zha, Min; Yu, Zhiyuan; Qian, Feng; Wang, Huiyuan; Li, Yanjun; Mathiesen, Ragnvald; Roven, Hans Jørgen (Journal article; Peer reviewed, 2018)The present work revealed that equal-channel angular pressing (ECAP) deformation combined with appropriate annealing could represent as an efficient route to modify immiscible as-cast microstructure of a monotectic Al–8Bi ... -
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. ... -
Improving ageing kinetics and precipitation hardening in an Al-Mg-Si alloy by minor Cd addition
Qian, Feng; Mørtsell, Eva Anne; Marioara, Calin Daniel; Andersen, Sigmund Jarle; Li, Yanjun (Journal article; Peer reviewed, 2018)This study reports significant improvements in both the age hardening kinetics and peak hardness of an Al-Mg-Si alloy by microalloying with 0.06 at% Cd. A detailed high-angle annular dark-field scanning transmission electron ... -
Precipitation in an A356 foundry alloy with Cu additions - A transmission electron microscopy study
Mørtsell, Eva Anne; Qian, Feng; Marioara, Calin Daniel; Li, Yanjun (Journal article; Peer reviewed, 2019)The influence of different Cu addition levels on the age hardening and precipitation behaviors in an Al356 foundry alloy during artificial aging treatment has been systematically studied. A detailed characterization of the ...
