Measurements on Single Subsized Specimens of Ferritic Alloys

CODEN: JTEVAB

Abstract

Fracture toughness tests on subsized, circular, compact tension specimens of ferritic alloys were performed at temperatures ranging from −192 to 427°C. Test results for 9Cr-1Mo show that the electropotential single specimen method agrees well with the multiple specimen method in determining the upper shelf J1c. The ductile-brittle transition temperature and lower shelf toughness of HT-9, tested at loading rates of 2.1 × 10−5 and 3.2 × 10−2 m/s. were also determined using the J-integral approach. The size criteria for valid J1c values, for a wide range of test temperatures, were satisfied by the subsized specimen used in this work.
