Effect of Normalizing on Microstructure and Mechanical Properties of EH36 Alloy

Abstract:

Normalizing is a kind of heat treatments, which have lower cost and higher efficiency. Through this process, the ship plate steel’s microstructure and performance can be promoted evidently. This article studies the effect of normalizing temperature on the microstructure and performance of controlled rolling and controlled cooling (TMCP) EH36 ship plate steel with the thickness of 15mm ,by mechanical properties text and optical microscopy. The results show that the comprehensive property of TMCP ship plate steel can be enhanced remarkably,although it’s hardness could be decrease,the plasticity of it can be improved obviously,especially the low temperature impact property. With the increasing of normalizing temperature,the grain grows,the impact property is decreased.
