Materials Engineering Laboratory

Course Description: This course covers the fundamentals of microscopic examination in detail, including: sectioning, polishing, etching, optical microscopy, and microstructural analysis of engineering materials. It also covers the determination of mechanical properties such as hardness, tensile strength, stress, and creep properties for both ferrous and non-ferrous materials and some polymeric materials, with a focus on the relationship between these properties and their internal structure. The course emphasizes the importance of these properties in the fields of manufacturing and engineering design, in addition to analyzing data and results from hardness, tensile, and heat-treated sample tests.
Credits: 1
Prerequisites: ME 251
