Grain refinement and strength enhancement in Mg wrought alloys: A review
Journal of Magnesium and Alloys, 2023 Low absolute strength becomes one major obstacle for the wider applications of low/no rare-earth (RE) containing Mg alloys. This review firstly demonstrates the importance of grain refinement in improving strength of Mg alloys by comprehensively ...

Impeding Nucleation for More Significant Grain Refinement [PDF]
Scientific Reports, 2020 AbstractGrain refinement has been a topic of extensive research due to its scientific and technological importance as a common industrial practice for over seven decades. The traditional approach to grain refinement has been to reduce nucleation undercooling by the addition of potent nucleant particles.

The effect of the austenite grain refinement on the tensile and impact properties of cast Hadfield steel [PDF]
Materials Research, 2018 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.
