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 ... -
Grain boundary segregation in Pd-Cu-Ag alloys for high permeability hydrogen separation membranes
Løvvik, Ole Martin; Zhao, Dongdong; Li, Yanjun; Bredesen, Rune; Peters, Thijs (Peer reviewed; Journal article, 2018)Dense metal membranes that are based on palladium (Pd) are promising for hydrogen separation and production due to their high selectivity and permeability. Optimization of alloy composition has normally focused on bulk ... -
Modelling the Age-Hardening Precipitation by a Revised Langer and Schwartz Approach with Log-Normal Size Distribution
Zhao, Dongdong; Xu, Yijiang; Gouttebroze, Sylvain; Friis, Jesper; Li, Yanjun (Peer reviewed; Journal article, 2020)A new numerical modelling approach integrating the Langer and Schwartz approach and log-normal particle size distribution has been developed to depict the precipitation kinetics of age-hardening precipitates in Al alloys. ... -
Modelling the Spatial Evolution of Excess Vacancies and its Influence on Age Hardening Behaviors in Multicomponent Aluminium Alloys
Wang, Xuezhou; Zhao, Dongdong; Xu, Yijiang; Li, Yanjun (Peer reviewed; Journal article, 2023)Excess vacancies play crucial roles in the precipitation of age-hardening precipitates in aluminium alloys, but their spatial evolution across grains during heat treatments is less known. In this work, a numerical model ... -
