위의 그림에서와 같이 이미 존재하고 있는 핵 생성위치에서 화학적 구동력 차이에 의한 마르텐사이트 변태는 Ms온도에서 일어난다. 그러나 Ms온도와 Ms0온도 사이에 실선으로 나타낸 응력하에서는 응력유기 마르텐사이트 변태가 일어날 수 있다. Ms0온도에

Heres to a brilliant future!
(cheering)
Here it is.
Thats wonderful!
Yeah.
They got the pivot pin in backwards.
Bev, you shouldve been there.
I was.
Well
What is Amorphous metal?
Polycrystalline grains of varying shapes and sizes
Misaligned planes of atoms slip past each other easily, absorbing energy and allowing dislocations to move, making deformation permanent.
Grain boundaries represent weak spots
Also called Metallic glasses or glassy metals
Cooled faster than atoms can rearrange into a crystal.
Dislocation movement obstructed s
hormone excess and is not synonymous with hyperthyroidism
But, the major etiologies of thyrotoxicosis are hyperthyroidism caused by Grave’s disease, toxic MNG, and toxic adenomas
2. Pathogenesis (cont.)
Polymorphisms in HLA-DR, CTLA-4, and PTPN22 (a T cell regulatory gene)
The concordance for grave’s disease
- in monozygotic twins : 20-30%
- in dizygotic twins : <5%
