Description

The tensile deformation and fracture characteristics of two ship plate steels and one low-alloy steel were determined from 25°C (77°F) to -196°C (-321°F). Both smooth and notched specimens were used and the true stress-natural strain data conform to the relation s=s_ºdⁿ in the strain interval 0.075 < d < 0.30. The strength coefficient s_º was to increase regularly with decreasing temperature, whereas the strain hardening exponent ? of the ship steels dropped to a relatively low value at low temperature.
