Continuous Hot‐Dip Galvanizing of Medium‐Manganese Third‐Generation Advanced High‐Strength Steels

Computational Design of Advanced Steels

The creation and use of computational models is seminal to the design of steels and associated processes and many such models have now become of generic value. We illustrate here a few examples that explain the vitality of the subject and how the methodology is leading to benefits for commerce and academia alike. There are some breathtaking developments which are critically assessed.

Strong Bainitic Steels by Continuous Cooling Transformation

Using metallurgical models, three steels were designed to obtain carbide-free bainitic structures in the as-rolled condition. Experimental castings were hot-rolled in a pilot mill and their austenite decomposition kinetics were measured using dilatometry. Tensile and Charpy impact properties were measured and the microstructures were characterised using X-ray diffractometry, optical and scannin...

A Multi-Population Parallel Genetic Algorithm for Continuous Galvanizing Line Scheduling

The steelmaking process consists of two phases: primary steelmaking and finishing lines. The scheduling of the continuous galvanizing lines (CGL) is regarded as the most difficult process among the finishing lines due to its multi-objective and highlyconstrained nature. In this paper, we present a multi-population parallel genetic algorithm (MPGA) with a new genetic representation called k near...

A Model for the Microstructure of Some Advanced Bainitic Steels

Some applications of phase transformation theory towards the exploitation of bainitic microstructures are discussed , with particular emphasis on the quantitative aspects of alloying element effects. Examples are used to illustrate the principles involved in the design of advanced bainitic alloys of the type currently under investigation in the steel industry.
