G-phase

G-phase strengthened iron alloys by design

Density functional theory (DFT) calculations were used to model G-phase precipitates of formula X6M16Si7 where X is Cr, Hf, Mn, Mo, Nb, Ta, Ti, V, W and Zr and M is either Fe or Ni. It was found that the occupancy of the d-orbital is correlated to …

Comment on 'The two-step nucleation of G-phase in ferrite', the authors: Y. Matsukawa et al. Acta Mater 2016; 116:104–133

Recently, Matsukawa et al. [1] published a paper investigating the nucleation and growth of Mn$_6$Ni$_{16}$Si$_7$ G-phase precipitates in duplex stainless steel using experimental and theoretical techniques. The G-phase cubic unit cells simulated by …
