Abstract

Decomposition of ferrite in austenitic stainless steel welds at 475 degree C (887 degree F) has been identified by using a new ultralow-load microindentation technique. During aging, a significant increase in hardness of the ferrite with time has been observed. The primary reason for the increase in hardness has been found to be the spinodal decomposition of ferrite into chromium-enriched alpha prime and iron-rich alpha . In addition, precipitation of G phase within the ferrite and M//2//3C//6 carbide at the gamma / delta interface has been observed.
