Abstract The current state of research in grain refining practices in cast titanium alloys has been reported. The grain refinement mechanisms in aluminum and magnesium alloy systems are relatively well understood, and it is known that both solute and nuclei are necessary to effectively initiate grain refinement. The grain size is expressed as a normalized fraction of the grain size in the unalloyed base material (CP titanium) and this normalized fraction is referred to as the relative grain size (RGS). The application of grain refinement models developed from the extensive work performed in aluminum and magnesium systems indicate that the observed grain refinement is attributed to solute effects, and none of the solute elements have changed the nuclei population that naturally occurs in CP titanium.
