... boxes are filled with specially bonded core sand and compacted much like the mold itself. Cores are placed in the drag, or bottom section, of the mold, and the mold is then closed by placing the cope, or top section, over the drag. Mold closing completes the production of the mold, into which the molten...

..., martensite is a form of ferrite that is supersaturated with carbon. Because of the very fast cooling rate, the carbon atoms do not have time to diffuse from their interstitial positions in the body-centered cubic (bcc) lattice to form cementite particles. Because martensite forms suddenly, there are no start...
