Papaefthymiou, Spyros (author), Banis, Alexandros (author), Bouzouni, Marianthi (author), Petrov, R.H. (author)The current work focuses on complex multiphase microstructures gained in CrMo medium carbon steel after ultra-fast heat treatment, consisting of heating with heating rate of 300 C/s, 2 s soaking at peak temperature and subsequent quenching. In order to better understand the microstructure evolution and the phenomena that take place during...journal article 2019

Banis, Alexandros (author), Hernandez Duran, E.I. (author), Bliznuk, Vitaliy (author), Sabirov, Ilchat (author), Petrov, R.H. (author), Papaefthymiou, Spyros (author)The effect of ultra-fast heating on the microstructures of steel has been thoroughly studied over the last year as it imposes a suitable alternative for the production of ultra high strength steel grades. Rapid reheating followed by quenching leads to fine-grained mixed microstructures. This way the desirable strength/ductility ratio can be...journal article 2019

Agarwal, G. (author), Gao, H. (author), Amirthalingam, M. (author), Hermans, M.J.M. (author)Susceptibility to weld solidification cracking in transformation-induced plasticity steel sheets was studied using a modified standard hot cracking test used in the automotive industry. To vary the amount of self-restraint, bead-on-plate laser welding was carried out on a single-sided clamped specimen at increasing distances from the free...journal article 2018
