Metallurgical and Materials Engineering Exam Specifications
As of April 2012
A few general points noted about the exam, which are followed by the detailed specifications.
• The exam is an 8-hour open-book exam. It contains 40 multiple-choice questions in the 4-hour morning session, and 40 multiple-choice questions in the 4-hour afternoon session. Examinee works all questions.
• The exam uses both the International System of units (SI) and the US Customary System (USCS).
• The exam is developed with questions that will require a variety of approaches and methodologies, including design, analysis, and application.
• The knowledge areas specified as examples of kinds of knowledge are not exclusive or exhaustive categories.
• The exam will include questions that are independent of the type of material and questions that are related to specific materials. The materials-specific questions will be distributed in the following three groups:
a. Approximately 50% of the material-specific questions address ferrous materials, defined as stainless steel, cast iron, carbon steel, and alloyed steel.
b. Approximately 30% of the material-specific questions address light and nonferrous materials, defined as titanium and titanium alloys, aluminum and aluminum alloys, copper and copper alloys, intermetallic alloys, precious metals, refractory alloys, superalloys, and other nonferrous metals.
c. The remaining 20% of the material-specific questions address ceramics, polymers, composites, and electronic materials, including glasses, functional ceramics, engineering ceramics, elastomers, thermoset, thermoplastic, composites, silicon, and other semiconductor materials.
