EPRI database for environmentally assisted cracking (EDEAC)

Abstract

The EDEAC draft report presents the current status of the EDEAC System. The report is divided into three sections. A brief summry of the project is presented in Section 1 to orient the reader and potential database user with the development steps that were required to originate and maintain the system. Also within this introductory section are several appendices that cover the contents of the database and present data source information. The appendices include (1) a bibliography by author and/or source, (2) an author summary by alloy and test type, and (3) a database summary by alloy and test type. Section 2 is the EDEAC User's Guide. This section contains all the instructions and examples necessary to use EDEAC. Sufficient system details are presented so that a user can learn the procedures to access the system and search for and retrieve data. These online procedures permit the generation of reports in graphical and/or tabular formats. Section 3 of the report contains a review of the stainless steel/water data to demonstrate the influence of various parameters - temperature, test frequency, stress ratio, and oxygen content of the water on the fatigue crack growth of 304 stainless steel. The data used formore » this study were retrieved directly from EDEAC in the graphical formats shown to provide rapid data comparison. 28 figs.« less
