The interstitial alloy between carbon and iron has a complex phase diagram ... alloys have a composition close to the Eutectoid composition: Fe - 0.77 wt% C. The transition that determines the ...

"The material composition controls the phase stability ... can help disrupt those column-like grains and refine the grain structure." Understanding the material properties of the starting alloy ...

The hydrophilic head is composed of a choline structure (blue) and a phosphate (orange). This head is connected to a glycerol (green) with two hydrophobic tails (purple) called fatty acids.

For the hypereutectoid composition shown by the vertical green bar the material enters the two phase austenite + cementite zone prior ... proeutectoid cementite on the grain boundaries. This structure ...
