Long time expositions at high temperatures
Long time expositions at high temperatures
(OP)
Significant micro structural alterations due to long time expositions at high temperatures that can result in imperfections of metallurgic origin, include:
1-Graphitisation, sigma phase, annealing embrittlement.
2-Grain growth, Graphitisation and mechanical fatigue.
3-Hardening, cavitations and embrittlement.
4-Sensitisation, graphitisation and erosion
Which would be the correct answer for the above statement?
Forum contributions would be appreciated

RE: Long time expositions at high temperatures
Which test is this from?
RE: Long time expositions at high temperatures
In lieu of the term annealing embrittlement, this should be called thermal embrittlement.
RE: Long time expositions at high temperatures
Although interesting the subject is arguable
My question is from an American test form of a course formation action related with Heaters & Boilers. As the question is vague and the option answers are very similar the choice for the correct answer is not easy.
My option goes for the option 1 but I am not sure if it is the correct one.
Thank you for the empathy
