Microalloying in steels is about a century old. The attractiveness of microalloying is that it allows the reduction of costs by suppressing heat treatments and improving strength, weldability (reduction of C and Mn), and toughness (grain refinement). The use of Nb, V, and Ti, either as single micro-additions or in combination, together with thermomechanical processing and accelerated cooling, has been the base for the development of high strength low alloy (HSLA) steels. It can be estimated that these steels now represent 10% to 15% of the world’s steel production.
The progressive development of HSLA steels has been accompanied by intensive research providing the required metallurgical support. As a result, numerous international conferences have been entirely dedicated to this particular type of steel, and countless reviews and journal papers have been published in this field. Nevertheless, the subject remains of interest and is faced with both old and new challenges, such as:
- The need for improved microstructural homogeneity and combination of properties: strength, weldability, and toughness of the base material and at the HAZ.
- Close control of additions and use of tailored combinations of microalloying elements, adapted specifically to the plant conditions and product format.
- Optimized adaptation to more recent production technologies, such as near net shape and direct rolling, and the production of high strength high gauge sheets and sections.
Microalloying is also applied in advanced high strength steels (AHSS), such as dual phase (DP) and transformation induced plasticity (TRIP) steels, in martensitic plates and sheets (ultrahigh strength steels (UHSS)), and in engineering steels. The challenges are driven by the same general idea of acquiring improved material performance at a minimum cost.
Papers on recent advances and review articles, particularly related to the most challenging aspects of the use of microalloying, are invited for inclusion in this Special Issue on "Microalloyed steels".

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 papers will be 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 100 words) can be sent to the Editorial Office for announcement on this website.
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 1200 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.
