FATIGUE-APPEARANCE-TRANSITION TEMPERATURE (FATT)
FATIGUE-APPEARANCE-TRANSITION TEMPERATURE (FATT)
(OP)
1) Can someone explain how to calculate FATT for a given metal ?
2) Is it a link with a Charpy-V Transition Curve Temperature ? Please explain ...
3) Any reference documentation about FATT will be appreciated .
Sincerely,
A_Tsampalas

Your question is too board for this forum. There are various web sites that can explain further;

Scroll to the article of interest regarding brittle fracture.

RE: FATIGUE-APPEARANCE-TRANSITION TEMPERATURE (FATT)
Thanks for your answers.
I know how to obtain CV ductile-to-brittle transition temperature curves .
I have never used FATT .
In found documentation, the writer suggests :
" After CV specimens were tested...From the fractured surfaces of the specimens, the FRACTURE-APPEARANCE-TRANSITION TEMPERATURE at 50 % cleavage (FATT 50) can be determined ".
As I am not acquainted with FATT, the subject (previous affirmation) seems unclear .
Can you please clarify ?
