**About the Special Issue Editors**

**Nima Haghdadi** is a research fellow at UNSW Sydney, Australia. He was awarded his Ph.D. in 2017 from Deakin University (Australia) for a thesis on processing of duplex stainless steels. He is a former Victoria Fellow and Alfred Deakin Research Fellow, and the recipient of Thermo Fisher Scientific Cowley-Moodie and Acta Materialia student awards. He was also the runner up in the James Clerk Maxwell Writers Prize in the *Philosophical Magazine* in 2017. Dr Haghdadi's main interest is engineering of microstructures of metallic materials including steels during conventional processing and additive manufacturing for advanced mechanical and corrosion properties.

**Mahesh Somani** is an Adjunct Professor at the University of Oulu, Finland. During his academic and research career spanning over 35 years, he has authored over 150 technical papers. In addition, he has authored 20 technical reports and has 2 patents to his credit. Dr. Somani established his career at the Defence Metallurgical Research Laboratory (DMRL), Ministry of Defence, India, during 1982–1998 in the capacity of Senior Scientist working mainly in the field of aerospace materials for gas turbine engines. At the University of Oulu (since 1999), his academic and research interests have mainly focused on physical simulation and modelling of hot deformation processes of steels and other materials, accelerated cooling/direct quenching, and phase transformation in steels, technology of alloy steels, static and dynamic restoration mechanisms, dynamic materials modelling and development of processing maps, and strength of metallic materials.
