Crack형 저온균열
1) Quenching Crack형 저온균열의 특징
중.고탄소강이나 그 합금강을 용접하는 경우, 냉각 도중 약 100oC 전후에서 마르텐사이트 변태에 의한 균열이 발생하는 경우가 있다. 이것을 Quenching Crack형 저온 균열이라 한다. 이러한 균열의 특징은 다음과 같다.
- 수소와 무관하며 Quenching Crack과
1 GPa
Elastic modulus Nanoindentation > 6 GPa
Adhesion Tape pull, modified-edge lift-off Delamination-free
Disavantages
Weakens mechanical properties
Lower thermal conductivity
Narrow pore distribution to ensure dielectric constant is homogeneous and isotropic
Pores need to be closed cells to prevent crack propagation and moisture absorption
Need to add silica to seal surface pores

One of these days youre gonna be
as good a cook as Ma!
Well, Im learnin, tryin!
Thats what I keep tellin him! Corie Sue

We like to call it "analysis".
Alright. What are these indications that somethings brewing out our way?
Theres no hard clues yet. What do you have, Joe?
