Grain refinement of primary silicon in hypereutectic Al-Si alloys by different P-containing compounds [PDF]

open access: yesChina Foundry, 2021
The grain refinement behavior of Si-3P, Si-25Mn-10P, and Al-10Si-2Fe-3P master alloys on hypereutectic Al-24Si alloy was studied. Microstructure analysis indicates that the P-containing compounds in the three master alloys are SiP, MnP, and AlP ...

The grain refinement of 1070 alloy by different Al-Ti-B mater alloys and its influence on the electrical conductivity

open access: yesResults in Physics, 2019
The excellent grain refinement effectiveness and good electrical conductivity is difficult to be simultaneously obtained due to the influence of both the grain boundary and excessive Ti in the usually used refiners, such as Al-5Ti-1B master alloy.
