Effect of Subcritical Quenching on Microstructure and Mechanical Properties of EH36 Alloy

Abstract:

Subcritical quenching is a kind of heat treatments, which have good strength and higher Plastic toughness. Through this process, the ship plate steels microstructure and performance can be promoted evidently. This article studies the effect of subcritical quenching 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, its hardness and plasticity could be improved obviously,especially the low temperature impact property. With the increasing of quenching temperature,the grain grows,the impact property is decreased.
