Examples
In a hypereutectoid composition (greater than 0.8% carbon), the carbon will first precipitate out as large inclusions of cementite at the austenite grain boundaries and then when the composition left behind is eutectoid, the pearlite structure forms.
There is no thermal activation energy for the transformation from austenite to martensite.
The carbon no longer fits within the FCC austenite structure, resulting in an excess of carbon.
The second most common austenite steel is the 316 grade, also referred to as A4 stainless and called marine grade stainless, used primarily for its increased resistance to corrosion.
