Welding and Joining of Advanced High-Strength Steels (3rd Edition)

Dear Colleagues,

Nowadays advanced high-strength steels (AHSSs) are being predominantly employed by the automotive industry. Among the main advantages, AHSSs provide improved fuel efficiency (due to weight reduction by downgauging) and accomplish passenger safety requirements (enhanced crashworthiness behavior) without compromising its properties. The AHSS family includes the following types of steel: Dual Phase (DP), Complex-Phase (CP), Ferritic-Bainitic (FB), Martensitic (MS), Transformation-Induced Plasticity (TRIP), Hot-Formed (HF), Twinning-Induced Plasticity (TWIP), boron-based Press Hardened Steel (PHS), and Quenching and Partitioning (Q&P). They possess sophisticated and unique multiphase microstructures that provide them with extraordinary strength, ductility, toughness, fatigue, and/or a combination of such properties.

Welding and joining of AHSSs is challenging, particularly when choosing a suitable technique according to established requirements (e.g., portability, cost, heat input, welding speed, joint and design restrictions, etc.). There are numerous available technologies utilized for joining AHSSs, including the following: resistance spot welding (RSW), laser welding, friction stir spot welding (FSSW), arc welding processes (GMAW, TIG, plasma), arc stud welding, high-frequency induction welding (HFIW), magnetic pulse welding (MPW), brazing procedures (GMA, plasma, laser), adhesive bonding, hybrid welding, mechanical joining, etc.

This Special Issue on the welding and joining of AHSSs aims to cover various topics of interest, which include (but are not limited to) the following: microstructure–property relationships, welding metallurgy (weld pool solidification, phase transformations, etc.), performance and properties (strength, impact, fatigue), dissimilar metal joining (i.e., AHSS and others), forming and manufacturing of tailored welded blanks, weldability of AHSSs, progress in related welding processes, welding and joining process simulation, neural network applications, industrial applications, and weld inspection and repair.

Submissions of original research articles and reviews are invited for this Special Issue.

I look forward to receiving your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metals is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
