An Industrial example of Microscopic Examination For your own interest only, not required for this course: For a good industrial example of the relationship between microstructural characteristics of a Mg-Al-Zn alloy and the resultant material properties (eg. Tensile strength, ductility) of net shape molded parts (eg lap top covers, cell phone housings) are manufactured by Thixomolding, look up the following scientific paper, available through the UW library resources. (A librarian can help you find this e-journal paper) F. Czerwinski, et. al. (2001), “Correlating the Microstructure and Tensile Properties of a Thixomolded AZ91D Magnesium Alloy”,

Unformatted text preview: Acta Materialla , Volume 49, pp. 1225-1235. This paper includes various microscopic examination techniques we discussed in class including SEM, TEM and optical microscopy including several excellent images of microstructural features. The assessment of mechanical properties via tensile test (yield strength, % elongation etc) is also discussed. By relating the microstructural features to the material properties, one may predict the engineering performance of materials from simple observation under an optical microscope and computer analysis of the digitized photomicrograph assessing (grain size distribution, symmetry, microporosity etc.)...
