An Example Of The Performance Of Materials Engineering …This question hasn’t been answered yetAsk an expertThe object of study of Materials Science and
Engineering is the generation and application of

knowledge that relates composition, structure and processing of
materials with their

properties and performance in use (this object was represented in
the first class of the course in

form of a tetrahedron…). An example of the performance of
Materials Engineering is the evolution of steel

which are used in the manufacture of power transformers. The
following figure shows the evolution

with the time of a magnetic property (magnetic loss; the smaller
the more interesting it is

the steel for this application), according to the technology used
at each moment. Initially

[point (1)] only pure iron was used for this application and the
transformers had high

power loss values. Large loss reductions were achieved with the
addition of

small amounts of Si in iron [point (2)]. To further reduce power
losses,

grains were oriented in a preferential direction (texture control)
[point (3)]. laminating the

material up to 0.27 mm thick led to [point (4)]. Recently, to
reduce losses of

power, a laser beam scans the surface of the sample (refining)
[point (5)].

All steps described above were carried out to improve the
performance of this steel

(one of the vertices of the tetrahedron) in relation to magnetic
losses. Correlate points (2), (3), (4) and

(5) with the other three vertices represented in the tetrahedron
(composition, structure in the various

scales (if applicable, mention which scale…) and processing).
