The Influence of Grain Boundary Sulphides on Hot Ductility,

Abstract

The effect grain boundary sulphide precipitation on the hot ductility of a low-alloy ESR steel has been investigated within the temperature range 1000-1350 deg C. It was found that grain boundary sulphides on their own have little influence on hot ductility. However, longer exposure times at high temperatures, in the presence of a partially oxidizing atmosphere caused a considerable drop in ductility for test temperatures below 1200 deg C. The mechanism involving this loss in ductility was not determined. (Author)
