The effect of the austenite grain refinement on the tensile and impact properties of cast Hadfield steel [PDF]
This paper studied the effect of the austenite grain refinement on the tensile and impact properties of a cast Hadfield steel (12 % Mn, 1.2 %C and 0.65 % Si). The austenite grain refinement was obtained by hafnium inoculation.

Designing grain refinement passes for multi-direction forging: A phase-field crystal study
Multi-directional forging is an effective plastic deformation method for polycrystalline grain refinement, and the degree of refinement is closely related to the number of forging passes. However, the relationship between the degree of refinement and the

Grain refinement efficiency of a new oxide-containing master alloy for aluminium casting alloys [PDF]
In this study, grain refinement efficiency of a new oxide master alloy based on MgAl2O4 was demonstrated on an A357 alloy. The grain size of the reference alloy was reduced by 50-60% with the addition of the master alloy and introduction of ultrasonic ...
