Abstract
Because flake-like TiAl3 particles in Al–Ti–C master alloys prepared in a melt reaction method dissolve slowly when they are added into Al melt at 720 °C, Ti atoms cannot be released rapidly to play the assistant role of grain refinement, leading to a poor refinement efficiency of Al–Ti–C master alloys. A united refinement technology by Al–10Ti and Al–Ti–C master alloys was put forward in this paper. The rational combination of fine blocky TiAl3 particles in Al–10Ti and TiC particles in Al–Ti–C can improve the nucleation rate of α-Al. It not only improves the grain refinement efficiency of Al–Ti–C master alloys, but also reduces the consumption.
