Embrittlement in iron and steels

Materials Science and Technology

Interested in contributing a paper?

This special issue of Materials Science and Technology will include peer-reviewed articles focusing on ‘Embrittlement in iron and steels’. The Guest Editor is Dr Chiradeep Gupta, Bhabha Atomic Research Centre, India (joy_gupta71@yahoo.co.in).

The embrittlement of iron and steels is probably one of the most investigated research themes not only from an experimental standpoint but also more recently from the application of multiscale materials modelling techniques. A diverse range of computational techniques involving first principle calculations such as Density Functional theory (DFT), facilitates simulations of defect evolution in increasingly larger ensembles of material volume by application of techniques such as Molecular Dynamics, Dislocation Dynamics, and Kinetic Monte-Carlo, to Crystal Plasticity-FEM, Finite Element methods.  As a result these techniques collectively are capable of investigating diverse phenomena causing embrittlement in iron and steels over a wide range of time and length scales. One of the outstanding successes of the modern approach is to demonstrate the radiation embrittlement in reactor pressure vessel steels arising from the cluster formation of nano – precipitates of Cu. Several other embrittlement phenomena arising from the presence of hydrogen, liquid metal, segregation of Group IV-V elements, formation of unstable phases etc. are all being investigated from a bottoms-up approach shedding new light on the nature of their respective chronological events leading to loss of load bearing capacity. New techniques such as atom probe tomography provide the critical experimental evidence that corroborates the mechanisms obtained delineated from the various computational approaches.

This special issue is concerned with providing a modern view on embrittlement phenomena occurring in iron and steels. It attempts to showcase the recent outstanding success achieved in recent times in understanding the role of microstructural changes (eg. segregation and presence of precipitates) over different length scale, on engendering embrittlement in iron and its alloys using modern computational and experimental approaches.

We are inviting original contributions in the above context, to be submitted before the 5th May 2019. Our goal is to publish in October 2019.

 These contributions can be reviews, critical assessments, original research or short communications. Each contribution will be reviewed as a normal submission.
