Abstract:

The data indicate that the candidate steel HY-80 might justify fuller consideration for high temperature service where there is concern about a rapidly running low-energy shear fracture initiated by a large flaw. The Charpy V-notch energy values of steel A, however, are probably too low to assure immunity from catastrophic lowenergy shear fractures during service within the temperature range studied. Author
