And how will it be in the future? I'm quite interested on that major. Any answers would be helpful, thank you.
Materials engineering is becoming an extraordinary interesting field everyday, because materials engineering plays a vital role in all engineering applications. Here are some basic lines about Materials and Metallurgy engineering :
Materials engineer
Job description
Materials engineers are responsible for the research, specification, design and development of materials to advance technologies of many kinds. Their expertise lies in understanding the properties and behaviours of different substances, from raw materials to finished products. The field is also referred to as materials science or materials technology.

Materials science is an interdisciplinary field involving the properties of matter and its applications to various areas of science and engineering. This science investigates the relationship between the structure of materials at atomic or molecular scales and their macroscopic properties. It includes elements of applied physics and chemistry. With significant media attention focused on nanoscience and nanotechnology in recent years, materials science has been propelled to the forefront at many universities. It is also an important part of forensic engineering and failure analysis. Materials science also deals with fundamental properties and characteristics of materials.

Smart Materials are materials that have one or more properties that can be significantly changed in a controlled fashion by external stimuli, such as stress, temperature, moisture, pH, electric or magnetic fields.
There are a number of types of smart material, some of which are already common. Some examples are as following:
