Welding and Joining of Advanced High-Strength Steels (2nd Edition)

Dear Colleagues,

Nowadays advanced high strength steels (AHSS) are being predominantly employed by the automotive industry. Among the main advantages, AHSS provide improved fuel efficiency (due to weight reduction by downgauging), and accomplish passenger safety requirements (enhanced crashworthiness behavior), without compromising the overall properties. The AHSS family (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 Steels, PHS; and Quenching & Partitioning, Q&P), possess sophisticated and unique multiphase microstructures that provides them with extraordinary strength, ductility, toughness, fatigue, and/or a combination of such properties.

Welding and joining of AHSS is challenging; in particular, when choosing the adequate technique according to established requirements e.g., portability, cost, heat input, welding speed, joint and design restrictions, etc. There is an ample number of available technologies utilized for joining AHSS such as 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 welding and joining of AHSS aims to cover various topics of interest (but not limited): microstructure-property relationships, welding metallurgy (weld pool solidification, phase transformations, etc.), performance and properties (strength, impact, fatigue), dissimilar metal joining (i.e., AHSS-others), forming and manufacturing of tailored welded blanks, weldability of AHSS, progress in related welding processes, welding and joining process simulation, neural network applications, industrial applications, weld inspection and repair.

In this Special Issue, you are invited to submit original research articles and reviews.

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-anonymized 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.
