There are many directions of materials, such as polymers, metals, inorganic nonmetals, ceramics, metallurgy, physical and chemical composite materials, and many finer powders. As far as our school is concerned, although the major of materials is divided into detailed directions, the courses of materials are basically the same. The following is the usual schedule. It can be seen that in fact, the undergraduate course of materials science is very one-sided and basically learns everything. If you want to learn material physics, you should also learn thermodynamics, statistical physics, quantum mechanics, functional material physics, crystal X-ray, solid state physics and so on.
The postgraduate entrance examination rate of materials major is very high, because the undergraduate course is too shallow, but the prospect of postgraduate entrance examination is still good. Materials major is easy to publish papers, and the salary of graduate students is not bad, so as long as the subject has the intention of postgraduate entrance examination, you can consider this major, which is still very fragrant. Whether the material major is a sinkhole depends on whether you want to drill deep. The above is my personal opinion on this major, please forgive me if there are any shortcomings.
