It was shown that the weld ductility is significantly higher than that of the base metal when the grain size in the weld metal is 5–8 μm and the test temperature is above 400°C. An increase in the test temperature leads to a decrease in strength properties and an increase in plasticity. The most significant changes begin at temperatures above 150°C. An increase in strength and ductility happens simultaneously with a decrease in the test temperature. When testing sheets of 1565ch alloy with a grain size of 15–40 μm, abrupt changes in deformation are observed at room temperature as well. They disappear however at the test temperature above 100–150°C.

Thus, the range of losing stability is found to coincide with that in the crystalline lattice of the alloy for the hyperelastic models during the martensitic transformation B2→B19'.
