摘要：
The interrelation between ductility and cold resistance characteristics is considered, as which can be established by using a special characteristic, mechanical stability coefficient (a universal measure of the resistance of metal to ductile-brittle transition). It has been found that ductility cannot ensure the required brittle fracture resistance of metal, but only creates prerequisites for the attainment of the required mechanical stability. A condition for high mechanical stability is a wide stress range between the current strength of metal and brittle rupture strength.
