Unformatted text preview: ENSC 3313/MET 3343 EVALUATING A SIMPLE ALLOY MICROSTRUCTURE Lab Experiment 2 (BRING SAFETY GLASSES) OBJECTIVES 1. To cast an alloy sample. 2. To learn how to prepare an opaque sample for metallographic examination. 3. To use a microscope. 4. To interpret a simple multiphase microstructure. 5. To relate a multiphase structure to the appropriate equilibrium diagram. 6. To correlate a material micro/macro structure with the sample pre-history. 7. To appreciate that properties depend on the type, amount, size, shape, distribution and orientation of the phases present. INTRODUCTION The assignment involves the preparation of a binary alloy from its constituents and an interpretation of its microstructure. This experiment complements the classroom topics of phase equilibria, introduced in periods 13 and 14. This lab is meant to give you some understanding of the practical significance of microstructural details. The assignment provides a preview to the structure versus properties themes covered subsequently. details....
