Normalised low carbon manganese steel, taken transverse to directionality

Description

Low carbon steel with a microstructure consisting mostly of ferrite. Manganese is added to steel to remove oxygen and sulphur. It causes a reduction in the resulting grain size and hence the steel is tougher and stronger. This sample has been normalised, recrystallising the ferrite. This micrograph has been taken transverse to the directionality and hence the directionality present in the pearlite is not apparent

Normalised low carbon steel, showing directionality

Description

Wrought iron contains a very low amount of carbon. The resulting microstructure is therefore virtually all of the ferrite phase, since upon reaching the eutectic temperature virtually all of the austenite will have transformed to ferrite. The remainder of the microstructure consists of stringers of slag, which are unaffected by normalisation.

Normalised carbon steel

Description

Low carbon steel with a microstructure consisting mostly of ferrite with the darker pearlite regions around the ferrite grains. Upon cooling the steel the ferrite forms initially, either on austenite grain boundaries or inclusions. This causes carbon to be partitioned into the austenite. Eventually the remaining austenite will be at the eutectoid condition and the transformation to pearlite will then take place. This sample has been normalised, removing the directionality caused by casting

Eventually the remaining austenite will be at the eutectoid condition and the transformation to pearlite will then take place. Micrograph was taken transverse to direction of casting, therefore no directionality is seen.

Low carbon steel. The resulting microstructure is therefore virtually all of the ferrite phase, since upon reaching the eutectoid temperature virtually all of the austenite will have transformed to ferrite. This sample is taken from the thread of a wood screw, some directionality is observable due to the shaping of the item.
