THE accompanying photomicrograph (Fig. 1) shows the phosphide eutectic in a grey cast iron at 5000 diameters. This shows that the constituent which appears as dark markings at × 1000, and is still ...

The eutectoid phase transition in the iron carbon system takes place at 727 C. The three components in equilibrium at this temperature are Austenite, g, with the composition Fe - 0.77 wt % C, Ferrite, ...

DURING the course of an investigation into the austenite stabilization phenomena of iron–nickel alloys containing 1 per cent carbon, it became necessary to obtain some knowledge of the limiting ...
