Quantifying the grain boundary segregation strengthening induced by post-ECAP aging in an Al-5Cu alloy
Jia, Hailong; Bjørge, Ruben; Cao, Lingfei; Hui, Song; Marthinsen, Knut; Li, Yanjun (Journal article, 2018)Hardening on annealing (HOA) has been frequently observed in nanostructured metals and alloys. For nanostructured materials obtained by severe plastic deformation (SPD), HOA has been attributed to the reduction of dislocation ... -
Scanning transmission electron microscopy studies of precipitation in Al-Mg-Ge alloys
Bjørge, Ruben (Doktoravhandlinger ved NTNU, 1503-8181; 2011:234, Doctoral thesis, 2011)Precipitation in three Al-Mg-Ge(-Si-Cu) alloys has been investigated using transmission electron microscopy. The alloy compositions were chosen to be similar to previously studied Al-Mg-Si(-Cu) alloys to facilitate direct ... -
Soft particles assisted grain refinement and strengthening of an Al-Bi-Zn alloy subjected to ECAP
Jia, Hailong; Bjørge, Ruben; Marthinsen, Knut; Mathiesen, Ragnvald; Li, Yanjun (Journal article; Peer reviewed, 2017)With the aim to improve the strength of potential Pb-free Al-Bi based bearing alloys, an Al-6Bi-8Zn alloy was subjected to equal channel angular pressing (ECAP). To reveal the roles played by the soft Bi particles, an ... -
The deformation and work hardening behaviour of a SPD processed Al-5Cu alloy
Jia, Hailong; Bjørge, Ruben; Marthinsen, Knut; Li, Yanjun (Journal article; Peer reviewed, 2017)An Al-5wt.%Cu alloy supersaturated with Cu in solid solution was subjected to equal channel angular pressing (ECAP). The microstructuralevolution was systematically investigated by backscattered electron (BSE)imaging, ... -
