By slowly cooling to point 'k', the ferrite grains grow in size and diffusion of carbon takes place from ferrite regions into the austenite regions as shown in Fig. At this point it is seen that a network of ferrite estruturas metalicas surrounds each austenite estruturas metalicas.
Pearlite is a lamellar mixture of ferrite and cementite. As explained earlier, estruturas metalicas is soft and ductile and pearlite is hard and it imparts mechanical strength to steel.
The higher the carbon content, estruturas metalicas higher would be the pearlite content and hence higher mechanical strength. Conversely, when the pearlite content increases, the ferrite content decreases and hence the ductility is reduced.
The microstructure of ferrite-pearlite steels is given in Fig.
The white portion in Fig. At the Eutectoid point where the carbon content is 0.

Steel and its heat estruturas metalicas, Butterworths, Microstructures at c and d are not observed in structural steels. Ofcourse microstructures c and d are not observed in structural steels.
As mentioned earlier, increase in carbon content is not the only way to obtain increased mechanical strength. As, mentioned in the earlier section, the formation estruturas metalicas pearlite, which is responsible for mechanical strength, involves diffusion of carbon from ferrite to austenite.
In the annealing process sufficient time estruturas metalicas given for the carbon diffusion and other transformation processes to get completed.

Hence by full annealing we get larger size pearlite crystals as shown in the cooling diagram in Fig. It is very important to note that the grain size of crystal is an important parameter in strengthening of steel. The vast expertise necessary estruturas metalicas manufacture a steel structure and the increase of distance between … Continue reading Management of the Production estruturas metalicas Metal Structures: Structural Health Monitoring SHM is fundamental to identify the structural behavior, in particular of special structures, allowing the validation of design hypothesis, the development of more economical solutions and the prediction of deterioration.
In general, the existing structural health monitoring systems present a high cost when installed in current structures. This paper presents the concept of a new structural panel that can be adopted in both bridge decks and slabs of industrial plants.
