NB: They also help select materials for specific products and develop new ways to use existing materials.

7. Analytical skills:
Materials engineers often work on projects related to other fields of
engineering. They must determine how materials will be used and how they
must be structured to withstand different conditions.
Important Qualities for Materials Engineers
5
Math skills:
Materials engineers use the principles of calculus and other advanced topics
in math for analysis, design, and troubleshooting.

8. Problem-solving skills:
Materials engineers must understand the relationship between materials'
structures, their properties, processes, and factors affect the products.
They must also figure out:

 Why a product might have failed,
 Design a solution, and
 Then conduct tests to make sure that the product does not fail again.
NB: ME skills being able to identify root causes the failure.

9. Speaking skills:
While working with technicians, technologists, and other engineers, materials
engineers must state concepts and directions clearly. When speaking with
managers, these engineers must also communicate engineering concepts to

people who may not have an engineering background.
Writing skills:
Materials engineers must write plans and reports clearly so that people
without a materials engineering background can understand the concepts.

10. Professional Materials Engineers typically do the following:
• Plan and evaluate new projects, consulting with other engineers as necessary
• Prepare proposals and budgets, write reports, and perform other tasks
• Supervise the work of technologists, technicians, and other engineers
Duties of professional Materials Engineers
8
• Supervise the work of technologists, technicians, and other engineers
• Design and direct the testing of processing procedures
• Monitor how materials perform and evaluate how they deteriorate
• Evaluate the impact of materials processing on the environment
• Determine causes of product failure and develop ways of overcoming the failure.

12. Aerospace Engineers
Aerospace engineers design primarily aircraft, spacecraft, satellites, and missiles.
In addition, they create and test prototypes to make sure that they function
according to design.
Architectural and Engineering Managers
Careers Related to Materials Engineers
10
Architectural and engineering managers plan, direct, and coordinate activities in
architectural and engineering companies.
Biomedical Engineers
Biomedical engineers combine engineering principles with medical sciences to
design and create equipment, devices, computer systems, and software used in
healthcare.

13. Chemical Engineers
Chemical engineers apply the principles of chemistry, biology, physics, and math
to solve problems that involve the production or use of chemicals, fuel, drugs,
food, and many other products. They design processes and equipment for large-
scale manufacturing, plan and test production methods and byproducts treatment,
and direct facility operations.

and direct facility operations.
Chemists and Materials Scientists
Chemists and materials scientists study substances at the atomic and molecular
levels and analyze the ways in which the substances interact with one another.
They use their knowledge to develop new and improved products and to test the
quality of manufactured goods.

14. Electrical and Electronics Engineers
Electrical engineers design, develop, test, and supervise the manufacturing of
electrical equipment, such as electric motors, radar and navigation systems,
communications systems, and power generation equipment.
Electronics engineers design and develop electronic equipment, including
broadcast and communications systems, such as portable music players

15. Sales Engineers
Sales engineers sell complex scientific and technological products or services to
businesses. They must have extensive knowledge of the products' parts and
functions and must understand the scientific processes that make these products
work.
Physicists and Astronomers
Careers Related to Materials Engineers

Physicists and Astronomers
Physicists and astronomers study the ways in which various forms of matter and
energy interact. Theoretical physicists and astronomers may study the nature of
time or the origin of the universe. Some physicists design and perform
experiments with sophisticated equipment such as particle accelerators, electron
microscopes, and lasers.

16. Junior materials engineers usually work under the supervision of
experienced engineers.
In large companies, new engineers may receive formal training in classrooms
or seminars.

As engineers gain knowledge and experience, they move on to more difficult
projects where they have greater independence to develop designs, solve
problems, and make decisions.
Eventually, materials engineers may advance to become technical specialists
or to supervise a team of engineers and technicians.

17. Many become engineering managers or move into other managerial positions or
sales work.
An engineering background is useful in sales because it enables sales engineers
to discuss a product's technical aspects and assist in product planning,
installation, and use.
