The Space Lattice and Unit Cells
Every matter consists of atoms, molecules, and ions. If these atoms, molecules, and ions (micro-particles) are represented in a three-dimensional space-occupying certain specific points in space, then these arrangements are termed as space lattices and t…
Question

These questions are based on a high carbon stell with a composition of 1.5%C and 98.5%Fe

1)Name the phases present and calculate the amounts of these phases just above the eutectoid temperature.

2)With equilibrium cooling just below the eutectoid temperature calculate the total ferrite.
