Prediction of Mechanical Properties in the Sub-Critical Heat Affected Zone of AHSS Spot Welds Using Gleeble Thermal Simulator and Hollomon-Jaffe Model

Autor: Abdelbaset R. H. Midawi, Oleksii Sherepenko, Dileep Chandran Ramachandran, Shima Akbarian, Mohammad Shojaee, Tingting Zhang, Hassan Ghassemi-Armaki, Michael Worswick, Elliot Biro

Publikováno v: Metals, Vol 13, Iss 11, p 1822 (2023)

Measuring the mechanical properties of weld Heat Affected Zone (HAZ) remains one of the main challenges in the failure analysis of spot-welded components. Due to the small size of the HAZ and variation in the temperature history, different peak tempe

Autor: Abdelbaset R. H. Midawi, Meet Patel, Mohammad Shojaee, Kate Pearson, Oleksii Sherepenko, Hassan Ghassemi-Armaki, Elliot Biro

Publikováno v: Metals, Vol 13, Iss 3, p 491 (2023)

Third-generation advanced high-strength steels (3G-AHSS) are typically galvanized to prevent corrosion of the outer body structure. However, the zinc coating on the surface, combined with the locally elevated temperatures generated during the resista

Determination of resistance spot weld failure path in ultra-high-strength press-hardened steel by control of fusion boundary transient softening

Autor: Michael J. Worswick, Oleksii Sherepenko, Sven Jüttner, Anastasiia Zvorykina, Elliot Biro, Alireza Mohamadizadeh

Publikováno v: Journal of Materials Science. 56:14287-14297

The use of coated press-hardened steels (PHS) in body-in-white (BiW) components provides significant potential for weight reduction, but leads to decrease in joinability, thus creating challenge to produce welds meeting commercial quality requirement

Influence of surface layers on resistance spot joinability of partially hardened steel 22MnB5 with aluminum-silicon and zinc coatings

Autor: Maximilian Wohner, Niels Mitzschke, Oleksii Sherepenko, Iwan Schischin, Sven Jüttner, Vincent Schreiber, Philipp Wernlein

Publikováno v: Welding in the World. 64:755-771

One of the methods to achieve local change in material properties when producing high strength parts with tailored mechanical properties is variating temperature histories in the furnace prior to hot stamping. This causes changes in surface layer dev
