Engineering Science

202. Engineering Materials Laboratory This is the laboratory portion of ENGS 201. Performance in the laboratory will be incorporated in the grade received in ENGS 201. Three hour laboratory every second week.  Fall and Spring (Cr. 0)

Course Objectives:

The student will be able to:

  • Measure and study mechanical and electrical properties of materials (hardness, ductility, Young's modulus, tensile strength, breaking strength, yield strength, thermal conductivity, electrical conductivity).

  • Analyze crystal structures and measure unit cell constants of metals using x-ray diffractometry.

  • Obtain experimental cooling curve data to construct and analyze the phase diagram of a binary metal system.

  • Study the effect of time, temperature and cold-working on the recrystallization of brass samples.

  • Perform a Jominy end-quench test and analyze the results.

  • Develop the ability to communicate effectively through written reports.

Course syllabus:

Textbook:

J. Reynolds, Engineering Materials Laboratory Manual, Chemical Engineering Department, Manhattan College, 1999 (latest revision).

Topics:

  1. Introduction, technical communication skills, and laboratory safety,  1 three-hour lab period

  2. Microscope work, Rockwell hardness test and Tukon micro hardness test,  1 three-hour lab period

  3. Electrical and thermal conductivity measurements and an Instron tensile test,  1 three-hour lab period

  4. Determination of crystal structure by Debye-Scherrer and diffractometer  methods, 1 three-hour lab period

  5. Determination of phase diagram by thermal analysis,  1 three-hour lab period

  6. Study of the cold working an re-crystallization of brass,  1 three-hour lab period

  7. The Jominy end quench test and study of steel microstructures,  1 three-hour lab period

Computer usage:  During most of the laboratory sessions students make use of programs on a PC in the laboratory to generate results and statistical information on their data.  These programs may also be accessed from any networked PC outside of lab time so that the students can check their calculations.
