You are designing a critical component to be installed in a chemical plant, where corrosion resistance and high temperature performance are critical. As a result, a fully dense material is required. Because of the materials used in the system, the part can only be produced by powder metallurgy. Which powder metallurgy process would you use to produce a fully dense component?a) Hot Isostatic Pressing b) Sinter then Metal Injection Molding c) Cold Isostatic Pressing d) Press and Sinter Processes e) Metal Injection Molding
