Mechanical properties of structural alloys at temperatures down to −269°C
With decreasing temperatures the yield strength of all the alloys tested increases down to −253°C and then drops slightly at −269°C in almost all cases.
Alloy VT1-1 is not sensitive to stress concentrations, although its use is limited because of its relatively low strength.
Alloy AT2-2 has a high strength and plasticity and is insensitive to stress concentrations at all temperatures.
