Abstract : The objective of this investigation was to investigate the suitability of the notched slow-bend specimen as a substitute for the ballistic H-plate for evaluating the toughness of welded butt joints made in armor plate with high yield strength ferritic electrodes and one sustenitic chromium-nickel steel electrode were tested at various temperatures from 400 F to -290 F. For unwelded armor specimens, absorbed-energy transition occurred over a temperature range from -140 F to -200 F; for austenitic weld specimens, from -75 F to -110 F; and for the more promising ferritic weld specimens, from -75 F to -110 F.
