Effect of lattice mismatch-induced strains on coupled diffusive and displacive phase transformations
, 2006 Materials which can undergo slow diffusive transformations as well as fast displacive transformations are studied using the phase-field method. The model captures the essential features of the time-temperature-transformation (TTT) diagrams, continuous ...

Displacive model of deformation twinning in hexagonal close-packed metals. Case of the (90 deg, a) and (86 deg, a) extension twins in magnesium [PDF]
, 2016 A crystallographic displacive model is proposed for the extension twins in magnesium. It is based on a hard-sphere assumption previously used for martensitic transformations.

Materials and Corrosion, EarlyView.The corrosion performance of X12CrMoWVNbN10‐1‐1 steel in chloride environments dramatically depends on pH. Acidic conditions trigger intense surface degradation, whereas neutral and alkaline media foster the formation of a compact and stable passive film, drastically reducing both general and localized corrosion.

Martensitic transformation induced by cold deformation of lean duplex stainless steel UNS S32304 [PDF]
Materials Research, 2013 Lean duplex UNS S32304 is an austenitic ferritic stainless steel with pitting resistance equivalent number around 24-25. Its corrosion resistance is similar to AISI 316L steel, but with the advantage of a yield limit two times superior to conventional ...
