Conclusions

  1. 1.

    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.

     
  2. 2.

    Alloy VT1-1 is not sensitive to stress concentrations, although its use is limited because of its relatively low strength.

     
  3. 3.

    Alloy AT2-2 has a high strength and plasticity and is insensitive to stress concentrations at all temperatures.
