Conclusions
-
1.
The ultimate strength of steels Kh18N10T and 000Kh20N16AG6 in biaxial tension increases from 80–90 to 172–180 kg/mm2 with a drop of temperature from room temperature to 77°K and remains unchanged at 20–4.2°K. The elongation remains constant at 77°K (10.5–12.5%) and decreases to 5.8–8.5% at 4.2°K.
-
2.
More martensite is formed in biaxial tension than in uniaxial tension at the same degree of deformation.
