DOI: 10.1007/s40195-020-01026-y
Abstract: The kinetics of isothermal austenite (γ)-to-ferrite (α) transformation at various temperatures in Fe–2Mn and Fe–2Mn–0.5Mo (wt%) alloys is investigated via dilatometry experiments and phase-field modeling. It was interestingly found that Mo addition has a marginal… read more here.

DOI: 10.1016/j.matchar.2017.03.026
Abstract: Abstract Duplex stainless steels are not easily formable due to the different deformation behaviour of austenite and ferrite. The seamless tube making process cold pilgering provides deformation conditions that enable enormous plastic strains at room… read more here.
