Hypoeutectoid steel, normalised at 1100°C

Description

A hypoeutectoid alloy (carbon composition less than eutectoid). The first phase formed upon cooling from the austenite phase field is proeutectoid ferrite. Due to the lower solubility of carbon in ferrite, carbon is partitioned into the remaining austenite. At the eutectoid point the remaining carbon enriched austenite transforms to pearlite (a mixture of ferrite and cementite) which is the darker region of the micrograph. The proportion of pearlite is dependent upon the overall composition. The ferrite (light areas) is a good example of an allotriomorphic ferrite. This means that its shape does not reflect its internal crystalline symmetry as it nucleates on the austenite grain boundaries and hence follows the shape of the boundaries, the remaining austenite within the ferrite then transf

Fe, C 0.5 (wt%) steel, near a decarburised surface

Description

This is a hypoeutectoid steel (one that has a carbon composition below that of the eutectoid). During original cooling from high temperature, some ferrite was formed first on the prior austenite grain boundaries and the remaining carbon-enriched austenite then transformed to pearlite in a eutectoid reaction. The specimen was then exposed to a decarburising atmosphere (just air in this case). This might happen inadvertently, or it could be done deliberately if a softer surface is required for some reason. Material near the top of the micrograph, which was close to the free surface, is depleted in carbon and has become almost entirely ferritic. The depth to which there is significant carbon depletion depends on the time and temperature of the decarburisation treatment. It is given approximat

Fe, C 0.1 (wt%), hypoeutectoid alloy

Description

This is a hypoeutectoid alloy, which has been air cooled from the austenite phase field at 950 °C. The first solid to form is proeutectoid ferrite, its morphology being determined by the cooling rate. At slow cooling rates (furnace cooling) there is sufficient time for the carbon rejected from the austenite to diffuse and equilibrium solidification occurs. With faster cooling the microstructure also depends on the original austenite grain size.Fast cooling and large grain size favours ferrite forming as Widmanstätten side plates from the grain boundaries. Small grain sizes imply a high number of nuclei and hence the ferrite grows as grain boundary allotriomorphs. In this case air cooling is sufficiently slow to produce allotriomorphic ferrite. The majority of the austenite has changed to

Description

This SEM image shows that the ferrite phase in the pearlite has been selectively etched compared to the cementite. The cementite phase appears to protrude from the surface. Within the pearlite region there are several colonies in different orientations, indicating that the pearlite nucleated on grains of the primary ferrite.
