WebDec 13, 2014 · Bishop introduced a brittleness index (B 5) in terms of peak strength and residual strength, and the relative stress drop in the stress–strain curve can be used … WebOnly the sand cast alloy was brittle at low temperature. For most alloys the tensile strength, yield strength, elongation and notch tensile strength increased in the temperature range from 295 to 20 K. Ultimate and yield strengths of most alloys are less at 4 K than at 20 K. Discontinuous yielding is evident in all stress-strain curves at 4 K. healing grace church tulsa
