From: An unconventional hydrogen effect that suppresses thermal formation of the hcp phase in fcc steels
Schematic diagrams of the hydrogen effects on (a) friction stress and (b) free energy change for the hcp diffusionless transformation. T0 and TN indicates an equilibrium temperature of fcc and hcp phases and Néel temperature, respectively. MsH and AsH indicate Ms and As with hydrogen, respectively.
