In response to the demanding requirements of different sectors, such as construction, transportation, energy, manufacturing, and mining, new generations of microalloyed steels are being developed and brought to market. The addition of microalloying elements, such as niobium, vanadium, titanium, boron, and/or molybdenum, has become a key tool in the steel industry to reach economically-viable grades with increasingly higher mechanical strength, toughness, good formability, and weldable products. The challenges that microalloying steel production faces can be solved with a deeper understanding of the effects that these microalloying additions and combinations of them have during the different steps of the steelmaking process.
The steel industry continues to remain a highly dynamic sector that must repeatedly face new challenges. During recent years, key factors have been the consolidation of new technologies, the marketing of new steel grades and the development of new products. Innovation, cost-reduction and environmental conservation are challenges that all of the players in the steel world - i.e. industry, research and academia - have to confront every day. Microalloying is one of the principal actors in this struggle. Volume is indexed by Thomson Reuters CPCI-S (WoS).
This is a collection of papers presented at the joint conference of the 7th International Conference on High Strength Low Alloy Steels (HSLA Steels 2015), the International Conference on Microalloying 2015 (Microalloying 2015), and the International Conference on Offshore Engineering Steels 2015 (OES 2015). The papers focus on the exchange of the latest scientific and technological progresses on HSLA steels, microalloying steels, and offshore engineering steels over the past decades. The contributions are intended to strengthen cooperation between universities and research institutes, and iron and steel companies and users, and promote the further development in the fields all over the world.
The properties of steels depend critically on their microstructure. By examining the mechanical properties of steels in conjunction with microstructure, the first edition gave a clear description of the development and behavior of these materials - the very foundation of their widespread use. This new edition more explicitly links this theory with applications while retaining the style and purpose of its predecessor.
This volume provides a substantial background to microalloyed steels with a wide selection of applications, some of which are very recent. A well-illustrated practical guide, this book acts as a useful source of data and a concise account of the theoretical aspects of the subject. Both academic institutions and the world-wide steel industry will find it indispensable.

The recent decades have witnessed extensive research efforts towards the development of microalloyed steels and several conferences were held on microallyed steels and their applications. The steel industry has revived with multidimensional development in many countries, including India, and has emerged as a highly dynamic sector that continually has to face new challenges. Innovation, cost reduction, energy and raw material conservation are the key issues for steel industry, R&D centers and academic institutes. Microalloying 2007 organized as a part of year-long celebration of the sesquicentenary year of Bengal Engineering and Science University (Formerly, Bengal Engineering College) and diamond jubilee year of the Indian Institute of Metals, provides a forum for technical interaction among the related sectors for a critical review of the development on microalloyed steel and emerging technologies for newer applications and product development to meet the increasing demand of various industries. The conference proceedings comprise a keynote paper, invited papers and contributed papers covering the areas of alloy design, processing, deformation and damage, phase transformation, formability and texture, structure-property correlation, corrosion, and application of microallying technology to interstitial free steel, high strength low steel and multiphase steel.
The technology of microallyoing is now, at the end of the 20th century, widely accepted. This is possibly due to the attractive balance of properties which is achievable with the correct control of the interaction between steel chemistry and processing parameters. Microalloying is applied to a wide range of products and has two main goals: to improve the mechanical properties and to save costs.
