Focusing attention on material properties is crucial for the proper selection of engineering materials in order to target desired functionality and reliability at the desired cost. Similarly, applying an investigational knowledge based process that looks at damage phenomena involved is an effective way to seek cost-effective solutions which enhance reliability at the right product cost, thus targeting the customer’s needs. Applying both of these approaches, that are mainstreams of the applied metallurgy field, leads to the translation of customer needs into basic material requirements that will serve a successful engineering design phase.
