Course Description

A technical elective course in the Associate of Applied Science Degree in the Machine Manufacturing Technology program. Covers the selection of materials for modern engineering and technology applications; structure and properties of ceramics, polymers, composities; the materials properties of electrical, thermal, magnetic; and the economic, environmental and societal issues in materials science and engineering. Prerequisite: MCH 246.

Addendum to Course Description

This course will provide the student with an introduction to the engineering concepts and technologies from an engineer’s viewpoint of the principal materials utilized by industry. Discussion subjects include, Materials Properties and Product Attributes and Engineering Materials, in a lecture/lab environment.
  • In depth study of electrical, thermal and magnetic properties of materials.
  • Structures found predominantly in ceramics, polymers and composites.
  • Economic, environmental and societal issues in materials science and engineering

PREREQUISITE SKILLS AND KNOWLEDGE:
MCH 246  
n Lab, the emphases are safety, teamwork, data measurement/analysis, and lab documentation using computer applications. Hands-on labs develop tactile ability for preparation of metallographic samples for microscopic examination and photographic documentation of the microstructures of samples subjected to a variety of thermal processing that affect mechanical properties for steel and aluminum alloys.

Intended Outcomes for the course


This course is based on competency mastery. Each section is assigned to a specific competency. Sections may be independent or dependent on other sections. The following competency profile is based upon industry standards that have been established for this course: The student will be able to:
  • Describe the fundamental structure and related properties of individual materials, classified as metals, ceramics or polymers by free hand sketching and by calculation of specific physical and chemical properties.
  • Utilize textbook data from tables, charts, and graphs for gathering data needed for problem solution in homework and exams.
  • Relate textbook and lecture information to lab activities.
  • Follow directions and ask for needed help in order to achieve successful results in the lab.
  • Work safely in small teams during lab activities.
  • Use computer applications (including grammar/spell checks) for consistent and well-document lab write-ups.

This course is based on performance outcomes. The following performance outcomes are based upon established industry standards. The student will demonstrate knowledge and understanding of the following: IN THE LABORATORY:

  • The structure-property relationship underlying the Materials Science and Engineering (MSE) field of study.
  • Perform a variety of calculations that pertain to properties of materials, primarily electrical, thermal, magnetic and mechanical, primarily to non-metals and their alloys.
  • Sketch easy to visualize isometric or oblique pictorials of unit cells of common cubic and non-cubic non-metal crystal structures.
  • Perform the required Laboratory activities detailed in the Lab Content above, meeting or exceeding the minimum requirements for process and quality.

 

  • Understand the importance of safety and follow all safety procedures
  • Develop skills necessary for metallographic (microscopic) examination of metallic sample surfaces:
  • Perform consistent Rockwell and Brinell (indentation) hardness tests
  • Perform tensile testing
  • Perform fatigue testing
  • Perform impact testing
  • Perform creep testing
  • Perform other testing of a material properties – electrical, thermal, magnetic and optical
  • Photograph etched material samples with the digital camera attached to the microscope

Course Activities and Design

 
 
MCH 248 – Metallurgy III will be presented by means of audio-visual presentations, demonstrations, lab experiences, and research activities. The course activities and design emphasize the development of skills and knowledge outcomes prescribed by established industry standards. The identified outcomes will be achieved by means of individual and team activities.  

Outcome Assessment Strategies

 
POLICY - Student performance measurements are based on established industry standards. The various areas of study during the course will be evaluated by a variety of activities. Typical of those activities are the following;
1. READING ASSIGNMENTS - Information sheets, textbooks, journal articles and the learning resource center are potential sources of information that the student will reference as directed in the modules identified in the introduction. 
2. HOME WORK ASSIGNMENTS - Participation in individual or team structured problem exercises. The emphasis will be to provide introduction to the appropriate areas of study presented/discussed during the class and listed in the syllabus.
3. LAB ACTIVITIES - Participation in individual or team structured laboratory exercises and experiences. The emphasis will be to provide introduction to the appropriate areas of study presented/discussed during the class. Any make up activities must be made with the lab manager.
4. FINAL ASSESSMENT - A take home examination in the form of multiple choice, true/false, matching, short answer structure that addresses the subject areas presented/discussed during the class and listed in the course content guide.
5. ATTENDANCE at all scheduled class meetings is strongly encouraged and may be considered in the final grade assignment.  
The following schedule of weight will apply to the evaluation activities for this course.
