AUSTENITE GRAIN SIZE CONTROL IN UPSTREAM PROCESSING OF NIOBIUM MICROALLOYED STEELS BY NANO-SCALE PRECIPITATE ENGINEERING OF TiN-NbC COMPOSITE

摘要：

　　There is a growing demand for thicker gage pipes particularly for off-shore projects.Austenite grain size control in upstream processing before pancaking is essential to obtain excellent DBTT and DWTT properties in thicker gage product.This paper examines the basic science aspects of austenite grain size control by nano-scale precipitate engineering.
