Course DescriptionA technical elective course in the Associate of Applied Science Degree in the Machine Manufacturing Technology program. Covers selection of materials for modern engineering and technology applications; structure and properties of materials starting with fundamental atomic arrangements; microstructural control through thermal and mechnaical processing and effects of service environment. Prerequisite: MCH 245.
Addendum to Course DescriptionThis 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.
- Introduces the study of metallurgy where the macro or bulk properties of materials are related to its microstructure.
- In depth study of mechanical properties of metals are emphasized.
- Materials characterization on the basis of the type and strength of the primary interatomic bonding prevalent in the selected material.
- On another level of characterization, students will sketch three-dimensional cubic and hexagonal crystal
- structures found predominantly in metals.
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, 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-documented
- 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:
- The structure-property relationship underlying the metallurgy field of study.
- Perform a variety of calculations that pertain to properties of materials, primarily mechanical,
- primarily to metals and their alloys.
- Sketch easy to visualize isometric or oblique pictorials of unit cells of common cubic and non-cubic
- metal crystal structures.
- The Equilibrium Phase Diagrams (Binary systems)
- Kinetics of Solid State Binary Systems
- 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
- Watch chemical safety video and sign off sheet
- Develop skills necessary for metallographic (microscopic) examination of metallic sample surfaces:
- Perform consistent Rockwell and Brinell (indentation) hardness tests
- Perform tensile testing on the Tinius-Olson testing machine
- Perform quench and temper heat treatment on selected plain carbon and/or low alloy steels
- Perform hardness testing to compare the effects of quench media (air, oil, or water)
- Perform hardness testing to compare the effects of tempering time (holding temperature constant)
- Photograph etched steel samples with the digital camera attached to the microscope
- Perform solution heat treatment and precipitation/age heat treatments on selected aluminum alloys
Course Activities and Design
MCH 246 – Metallurgy II 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.
