Abstract

Abstract

The influence of rare earth elements on structure in casting tool steel has been investigated by using optical microscope,high temperature hardometer, SEM, TEM, electron probe.The results show that the addition of micro rare earth elements to low alloy tool steel can decreases relative content of gross carbide, improve the dispersion, refine the austenite grain and reduce the dendritic segregation of chromium.
