Effect of Inclusion and Filtration on Grain Refinement Efficiency of Aluminum Alloy
Yang, Jiawei; Xu, Yijiang; Bao, Sarina; Akhtar, Shahid; Tundal, Ulf; Tjøtta, Stig; Li, Yanjun (Peer reviewed; Journal article, 2022)It is well known that the filtration efficiency of ceramic foam filters (CFF) on aluminum melt can be significantly reduced by the addition of grain refiner particles under a high inclusion load. Also, it is usually ... -
Heterogeneous nucleation and grain growth of inoculated aluminium alloys: An integrated study by in-situ X-radiography and numerical modelling
Xu, Yijiang; Casari, Daniele; Du, Qiang; Mathiesen, Ragnvald; Arnberg, Lars; Li, Yanjun (Peer reviewed; Journal article, 2017)A comprehensive study on the heterogeneous nucleation and grain growth of Al-10 wt.%Cu alloys inoculated with Al-5Ti-1B was carried out. To further reveal the solute segregation stifling mechanism, in-situ near-isothermal ... -
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 ... -
P removal from Si by Si-Ca-Al alloying-leaching refining: Effect of Al and the CaAl2Si2 phase
Zhu, Mengyi; Yue, Shengying; Wu, Guixuan; Tang, Kai; Xu, Yijiang; Safarian, Jafar (Peer reviewed; Journal article, 2021)Phosphorus (P) is a critical impurity in metallurgical-grade Si that needed to be removed for solar-grade Si production. The Si-Ca-Al-P system is one of the most crucial alloy systems for Si refining, where P can be separated ... -
Silicon kerf loss as a potential anode material for lithium-ion batteries
Søiland, Anne Karin; de Meatza, Iratxe; Muguruza, Ane; Xu, Yijiang; Bellmann, Martin Pawel (Peer reviewed; Journal article, 2024)In this work, industrially processed silicon kerf loss (abbreviated to silicon kerf) from the photovoltaic industry is assessed as an anode material for the lithium-ion battery (LIB). The study includes both a characterization ... -
Understanding heterogeneous nucleation and predicting grain size in wire and arc additive manufacturing of steels with inoculation
Xu, Yijiang; Tranell, Maria Gabriella; Li, Yanjun (Peer reviewed; Journal article, 2024)Inoculation has become a common practice to achieve grain refinement in metal additive manufacturing, and its application in steels has been extensively investigated in recent years. However, the nucleation behavior of ...
