Integrated Model for Microstructural Evolution and Properties of Steel Plates Manufactured in Production Line.

Abstract

The mathematical model for the prediction of microstructural evoiution and mechanical properties shown in the previous report is integrated with the process models those calculate the strain and temperature distribution through thickness at multiple points in the plate during the rolling and the cooling steps for the adoption to a commercial production line. The experiments that cover the wide range of the chemical compositions and the manufacturing conditions of steel plates were conducted and the obtained results such as microstructures and mechanical properties of the plates were comparedwith the calculated results of the present integrated model. The main points of the present report are summarized as follows:
