REVISION OF THE TENSILE DATABASE FOR V-TI AND V-CR-TI ALLOYS TESTED AT ANL

The database for the tensile properties of unirradiated and irradiated V-(0-18) wt%Ti and V-(4-15) wt%Cr-(3-15) wt%Ti alloys tested at Argon ne National Laboratory (ANL) has been reviewed and, when necessary, re vised. A consistent methodology, based on ASTM terminology and standar ds, has been used to reanalyze the unpublished load vs. displacement c urves for 162 unirradiated samples and 91 irradiated samples to determ ine revised values for yield strength (YS), ultimate tensile strength (UTS), uniform elongation (UE), and total elongation (TE). The revised values for UE and TE are lower by 5 +/- 2% (strain) and 4 +/- 2% (str ain), respectively, than previously reported values, which included di splacements due to machine compliance. Revised values for YS and UTS a re consistent with previously published values in that they are within the scatter usually associated with these properties. (C) 1998 Elsevi er Science B.V.
