First of all, the in-service conditions must be characterized. 編輯課件13編輯課件14A second selection consideration is any deterioration of material properties that may occur during service operation. Finally, probably the overriding consideration is economics. 編輯課件15編輯課件16The more familiar an engineer or scientist is with the various characteristics and structure-property relationships, as well as processing techniques of materials, the more proficie
