The hypoeutectoid steel is the most ductile and the ductility has decreased by a factor of three for the eutectoid alloy. In hyper-eutectoid alloys the additional, brittle cementite on the pearlite ...

Both types of reaction occur by nucleation and growth (Fig. 3.14a), and rely on diffusion. Pearlite nuclei occur on austenite grain boundaries, but it is clear that they can also be associated with ...

While it cools through this zone Fe 3 C is deposited on the austenite grain boundaries and the austenite composition moves to the eutectoid value. When the alloy reaches the eutectoid temperature the ...

For example, manganese is added to combine with sulphur, but it is also a strengthener, while manganese and silicon are deoxidizers and aluminium is used as a deoxidizer and as a grain refiner, and ...
