Overview
Materials science is an interdisciplinary field that integrates scientific principles, such as physical and chemical ones, with (bio) engineering and mechanical ones to generate novel materials. With a degree in materials science, you may discover how various materials function and how to enhance them for various uses, such as coatings for spacecraft and food packaging.
What is the study of materials?
You will thoroughly grasp numerous materials and their uses in Materials Science, a hybrid course.
Your objective as a successful material scientist is to link the desired feature of a given material, such as brittleness, hardness, or flexibility, to the scientific factors that determine this property, such as its chemical composition.
Then, this information may be used in various technical disciplines, including (bio) medicine, construction, packaging, electrical, and many others. Your ability to create the best material for every application will help your understanding of engineering ideas.
Good university programs in materials science offer more specialized modules for evaluating the various physicochemical properties (elongation, stiffness, thermal behavior) and developing new materials, in addition to modules that concentrate on the sciences required for the course, specifically Chemistry, Physics, and Mathematics. The less strictly scientific content will be covered in programs with a stronger emphasis on materials engineering, which will also place more emphasis on themes like process and product design for industrial production.
Many programs offer hands-on opportunities to work on relevant projects during applicable sections or research periods. Depending on the course, such projects may be completed in a university, a research facility, or a business.
What you’ll discover when pursuing a bachelor’s degree is:
From university to university, materials science bachelor’s programs have different curricula. The courses generally offer an overview of the principles of various materials and foster an awareness of the essentials of chemistry, physics, and mathematics. You can expect to learn more about linear algebra, differential equations, and integrals in engineering-focused courses.
A variety of topics are often covered in Bachelor’s programs. Examples with common uses are provided below:
- Biomedicine (medical implants, biomimetic materials)
- Packaging (plastics, cardboard)
- Optics (solar panels, LEDs)
- Electronics (displays, circuits)
- Metallurgy (building, reactors)
- Ceramics (cookware, artificial teeth)
- Wood (furniture, construction)
- Nanomaterials (ultrahigh-strength materials, catalysts)
- Polymers (Kevlar, Nylon)
- Surface science
- Electronics all fall under this category (corrosion- or oxidation-resistant materials)
You will discover which materials are most frequently used for different purposes, how to characterize and analyze them, and how to enhance or create new materials using various techniques. Even at the undergraduate level, optional modules let you concentrate on the topics that interest you the most.
Then you will examine several material characteristics, including electrical, optical, crystallinity, shock resistance, etc. You will learn how to characterize these characteristics using various methods, such as thermal or atomic level methods.
Some programs also offer computer modeling modules. You may learn to forecast certain material qualities using computational simulations without needing a lab experiment. In other common courses, you may learn how to utilize CAD (computer-aided design) software.
Then, practical courses or projects are usually a part of any bachelor’s curriculum. Your Bachelor’s thesis, which is often required to graduate, will involve a research assignment where you’ll put the information you’ve learned thus far to use and experience what it’s like to be a material scientist for the first time.
What you’ll discover when pursuing a master’s degree is:
You will concentrate on a particular area in many, if not most, Masters in Materials Science & Engineering programs. While some programs allow you to pick your specialization through elective modules, others already have specializations. Every university has unique strengths, so before applying, review the program. The following are specific specializations: ceramics, metals, fuel cells, batteries, nanotechnology and catalysis, plastics (i.e., polymers), biomaterials, optics, and electronics.
In comparison to your Bachelor’s degree, postgraduate lectures will be more difficult and provide you the opportunity to go deeper into the subjects you are most passionate about.
A Master’s degree will often require you to do practical research for your thesis or dissertation or as part of an integrated industry placement into the program.
What should I understand before starting a materials science Ph.D.?
You will become an authority in your profession with a Ph.D. in materials science, but not everything will always go according to plan.
A doctoral degree is exceedingly difficult to obtain and demands a lot of perseverance. Numerous challenges will arise:
- Lab tests may not work.
- A planned research strategy may be too expensive or complex.
- An analysis may render your computer unusable.
- You may be working on a topic that is so novel that you are just unsure of where you are going.
However, everything is normal.
You may have a variety of tasks to do during your Ph.D., depending on the project’s subject and objective. Additionally, you will need to persuade a scientific publication or an industry partner that what you are doing is important. The level of competition may be great, but with a little imagination, you may stand out from the crowd.
All of this isn’t easy. However, if you want to pursue it, don’t allow the difficulties to stop you; instead, give it your all.
Career alternatives for graduates in the materials sciences
Particularly now that many firms are switching to more environmentally friendly methods and materials, materials scientists are in great demand. As a graduate, you have a wide range of job opportunities, albeit in some cases, you may face competition from physicists or chemists. Additionally, there are several options for both application fields and functions.
Research scientists (R&D), product/process development scientists, materials engineers, patent examiners, quality managers, CAD technicians, and manufacturing engineers are regular employment in any sector.
Then some roles are particular to certain fields:
- Metallurgist: You specialize in metals, as the name implies. Understanding the properties and applications of metals and alloys can help you contribute to enhancing their extraction and processing.
- Biomedical engineer: In this role, you’ll use your expertise in the medical industry. For instance, you may develop a surgical robot prototype or develop novel prostheses materials.
- Geotechnical engineers employ rocks to mitigate several dangers brought on by the environment (think of earthquakes or landslides). Understanding the sort of rock you are working with can help you propose answers and research the changes in a particular location to avoid tragedies.
- A polymer scientist is generally a chemist. However, a materials scientist interested in chemistry can also do this function. It is your job as a polymer scientist to build or change polymers at the molecular level for various uses.
Top justifications for studying materials science
A Materials Science & Engineering degree has several advantages because there are so many exciting advances and alternatives in this field. The strongest arguments for entering this field are as follows:
- It’s thrilling: Working with materials in various applications allows you to observe the results of your efforts directly. Every day might bring about a new finding as the field is still developing.
- It’s a flexible field: You can access various employment opportunities depending on your interests and talents.
- You’ll have excellent employment possibilities Materials scientists and engineers are in great demand across a range of businesses, and that trend is unlikely to reverse anytime soon.
- And you may work anywhere in the world: It’s usual for materials scientists to travel extensively in both industry and research. Ideal if you wish to reside and earn a living abroad!
- With your labour, you may produce something more quickly and affordably or invent something new that might save lives. A new substance has the potential to alter the planet!
