Abstract

The creep and rupture behavior of weld-deposited Type 16-8-2 stainless steel at 593°C was investigated over the time range from 3.6 × 104 s to 2.5 × 107 s. Equations relating stress (σ) to the time to rupture (tr ), the time to the onset of tertiary creep (tt ), and the time to produce a given creep strain (tεc ) were obtained:

ln tr = 81.3456 − 12.176 ln σ
ln tt = 80.0786 − 12.176 ln σ
ln tεc = Aεc − 13.0 ln σ
Aεc = 87.3633 + 1.32066 ln εc
  + 0.446428 [ln εc]2 + 1.08131 [ln εc]3
  + 6.96513 × 10−3 [ln εc]4
The experimental results indicate that the control of welding parameters (e.g. current, voltage, and travel speed) within reasonable ranges can yield weld deposits with consistent time-dependent properties. Limited data suggest that high temperature (1065°C) post-weld annealing significantly alters only the flow curve for plastic deformation, while long-term thermal exposure at an intermediate temperature (565°C) produces only minor changes in either the plastic deformation or creep behavior of the weld materials.
