EFFECT OF STRUCTURE AND CHEMICAL COMPOSITION ON THE LIFE OF STEEL

The authors conducted a systematic investigation of the effect of structural parameters (size of ferrite and austenite grains, dispersity, number, and shape of carbides) and also the chemical composition of the steel (amounts of carbon, nickel, and silicon) on the life. Among the numerous elements used for alloying of steels, nickel and silicon were selected because they have opposite effects on susceptibility to brittle fracture. Comparison of the structural characteristics, the effect of stress relaxation, and the mechanical properties with different types of loads and the life of the steel indicates no single-valued relationship between the life and the stress relaxation effect. This also holds true for other mechanical properties.
