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 (Journal article; Peer reviewed, 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 ... -
In-situ X-radiographic study of nucleation and growth behaviour of primary silicon particles during solidification of a hypereutectic Al-Si alloy
Xu, Yijiang; Deng, Yun; Casari, Daniele; Mathiesen, Ragnvald; Li, Yanjun (Peer reviewed; Journal article, 2020)Real-time observation of structure evolution in a hypereutectic Al-Si(-Cu) alloy under near-isothermal melt solidification condition was conducted by using in-situ micro-focus X-radiography. The nucleation, growth rate and ... -
Revealing the Heterogeneous Nucleation and Growth Behaviour of Grains in Inoculated Aluminium Alloys During Solidification
Xu, Yijiang; Casari, Daniele; Mathiesen, Ragnvald; Li, Yanjun (Peer reviewed; Journal article, 2019)An in situ X-ray radiographic study on the grain nucleation and grain growth of inoculated Al–10Cu and Al–20Cu alloys during isothermal melt solidification and directional solidification conditions with constant cooling ... -
Revealing the heterogeneous nucleation behavior of equiaxed grains of inoculated Al alloys during directional solidification
Xu, Yijiang; Casari, Daniele; Mathiesen, Ragnvald; Li, Yanjun (Journal article, 2018)An in-situ study on the directional solidification of an inoculated Al-20 wt%Cu alloy under well-controlled constant cooling rates and temperature gradients has been carried out using a microfocus X-radiography set-up. The ...
