Refinement and development of homogeneous microstructures through the thickness of heavy products in V-steels

Objectif

Acicular ferrite microstructure, which provides effective grain (structural) refinement, is one of the most desired microstructure that improves both strength and toughness. Recent experimental results strongly indicate that a fine acicular ferrite microstructure can be obtained by proper use of vanadium microadditions.

To develop such a microstructure homogeneously through the thickness of heavy products, a new cooling strategy, called Alternate Water Cooling, is proposed to cool in-depth heavy products.

In this work, the effect of V and the cooling process in promoting an acicular ferrite microstructure homogeneously distributed through the thickness of heavy plates and long products will be investigated as a method for improvement of both strength and toughness.
