Conclusions 1. All the alloys investigated except É1659 and OT4 retain their ductility down to the temperature of liquid hydrogen. In the case of VNS2 one observes a small increase of the elongation with decreasing temperature. Particularly high ductility at low temperatures down to 4.2°K are characteristic of the copper-base alloys. 2. In all alloys the resistance to plastic deformation and the ultimate strength increase with decreasing temperatures. The increase is greatest for the VNS2 alloy. 3. Iron alloys (except for VNS2) are similar to materials with a body-centered cubic lattice, for which the decrease of elongation, increase of the yield strength, and an insignificant change in hardening with decreasing testing temperatures below 273°K are quite characteristic. The anamalous changes in the ductility and strength of the VNS2 alloy probably are due to the change of the phase composition resulting from low-temperature deformation.
