AN INVESTIGATION OF THE CRACK-PROPAGATION RESISTANCE OF HIGH-STRENGTH ALLOYS AND HEAT-RESISTANT ALLOYS

Abstract

The tensile properties and crack-propagation properties of 0.050 in.-thick D-14 Nb-alloy sheet were determined over the temperature range from -300 F to 1200 F. No brittle-ductile transition was found at temperatures down to -300 F. Very slight evidence of strain aging manifested by increased strength properties and serrated plastic stress-strain curves, were noted at two elevated temperatures 600 F and 1100 F. (Author)
