reological whore of 400 ° c

[folle76]

Hello.
I have to model the stress-strain curve with an elastic-linearly plastic pattern for the ste355 1.0577. at room temperature everything ok. I go with stresses and engineering deformations to yield and break. but going up with the temperature, is there any formula that gives me an estimate of the above values?
from .jpg you may understand better what I mean. Does anyone have experience in static field design at 400°c for steels? or, at least, does it list me briefly to what problems should you pay attention? Thank you.

Hi crazy,
I'm interested in that. I think there are formulas like larson miller and creep analysis in a controlled environment. I try to see what I can find around and I'm studying the subject myself.

If you want an immediate response, the solutions are two:
1) make traction tests at 400°c and get the chart
2) send an email to the unsider and ask if they give you any indication or if you turn a contact of a competent metallurgist on the topic

when I was doing the uniformity, they made us perform traction tests with the special machine and on the pc the curve was made in real time... I don't know if you're looking for something like that, maybe in some college you can find help

you can hear directly the european creep collaborative committee that deals with the hot run and ask if they give you the curve or better the curves of larson miller effort/time
