METALLURGY AND MATERIALS ENGINEERING

Metallurgical and materials engineers extract, process, refine, combine, and manufacture natural substances to create new materials that are stronger and resist corrosion. Metallurgical engineers work with metal only. Teams of metallurgy and materials engineers created the US Air Force’s “stealth” technology that makes a fighter plane’s surface nearly invisible to radar.

MECHANICAL ENGINEERING

Mechanical engineers use mechanics and energy principles to design machines such as engines and motors. Many mechanical engineers work in the areas of air-conditioning and refrigeration, automotives, manufacturing, welding, and robotics. They designed the robotically controlled braces that people with disabilities use to walk
