OBJECTIVE The objective of this lab is to become familiar with the grain structure of 1008 Plain Carbon Steel and Ductile Cast Iron, and to gain experience in grinding, polishing, and etching metal samples. In addition, another objective is to become more familiar with techniques used to examine, microscopically, common metallic materials. Finally, I hope to be able to determine the size of grains in the steel sample and to determine the size of the carbon nodules in the cast iron sample. Samples -1008 Plain Carbon Steel Sample -Ductile Cast Iron Sample Microscope Grinder SiC paper (grades 600, 800, 1200) Cloth Paper (Al2O3) Chemical Etching PROCEDURE Preliminary: Session 1 1. First, you must cut your metal materials, and then mount them in plastic. Secondly, you have to take both of your samples and grind them at six hundred, eight hundred, and twelve hundred. You will need to remember to rotate the sample
