Continuous Cooling of CMnSi TRIP Steel

TRIP steel

A combination of neural networks and genetic algorithms has been used to design a TRIP assisted steel in which the silicon concentration is kept low. In this context, the steel has a novel microstructure consisting of d ferrite dendrites and a residual phase which at high temperatures is austenite. This austenite can, with appropriate heat treatment, evolve into a mixture of bainitic ferrite an...

The Use of Water Cooling during the Continuous Casting of Steel and Aluminum Alloys

In both continuous casting of steel slabs and direct chill (DC) casting of aluminum alloy ingots, water is used to cool the mold in the initial stages of solidification, and then below the mold, where it is in direct contact with the newly solidified surface of the metal. Water cooling affects the product quality by (1) controlling the heat removal rate that creates and cools the solid shell an...

Effects of High Cooling Rates on the Improvement of Continuous Steel Casting Microstructure

A. Mahmutović, University of Zenica, Faculty of Metallurgy and Materials, Zenica, Bosna and Herzegovina This paper has r esearched into the infl uence of trace elements in st eel, combined with new casting pr ocesses, on the microstructure and micr o-segregation phenomenon in the case of struc tural steel. Thermocalc sof tware has been applied for calculation of steel phase. In the paper, close...
