Abstract

The creep tests have been conducted for ultra pure ferrite stainless steel 409M at 650 and the applied stress ranging from 60MPa to 80MPa. The creep deformations and rupture behaviors have been investigated. The results show that a brief primary creep stage is characterized under the condition of test. A larger applied stress caused a higher steady state creep rate and a shorter rupture time at 650 . The steady-state creep rate can be described by creep constitutive equation with the creep stress exponent n of 2.34, which shows a creep mechanism involving grain boundary sliding. The creep rupture data show an excellent agreement with the Monkman-Grant relationship. The fracture pattern belongs to transgranular ductile fracture.
