2022-11-27 Distribution Behavior of B and P during Al-Si Melt Directional Solidification with Open-Ended Crucible doi:10.57760/sciencedb.06494 en Distribution behavior of B and P during directional solidification of Al-20Si, Al-30Si and Al-40Si alloys has been investigated. Macrostructure of the Al-Si alloy ingots and concentration profile of elements B and P reveal that the elements segregate to eutectic Al-Si melt during growth of primary Si flakes, and P gradually segregates to the top of the ingots during directional solidification. An apparent segregation coefficient, k(a), is introduced to describe the segregation behavior of B and P between the primary Si and the Al-Si melt and compared with thermodynamic theoretical equilibrium coefficients. The apparent segregation coefficients of B and P decrease with increase of solidification temperature. solvent refining; Al-Si alloy; directional solidification; apparent segregation coefficient Xiaolong Bai Boyuan Ban Jingwei Li Zhijian Peng Jian Chen PUBLIC https://creativecommons.org/licenses/by-sa/4.0/ dataset http://www.doi.org/DOI 10.1515/htmp-2016-0127 Science Data Bank
