Abstract—The brittle failure of metals at low temperatures is analyzed. It is shown that the ductile–brittle transition temperature depends on the lattice parameter: with increase in the lattice parameter, the ductile–brittle transition temperature falls. The brittle failure of a material depends on its crystal lattice and its electron structure and on whether impurities are present at the grain boundaries. Increase in brittle strength of steels by optimization of their heat treatment is proposed.

Keywords:

low-temperature strength brittle failure lattice parameter heat treatment
