FERRITO-MARTENSITIC DUAL-PHASE STEEL OBTAINED IN AN INTERCRITICAL QUENCHING IN MAGNETIC FIELDS. STRUCTURE AND MECHANICAL PROPERTIES

摘要

The structure and mechanical properties of dual-phase steels that are obtained through quenching from intercritical temperature range depend on the chemical composition of material technological parameters of intercritical quenching. In this paper, the authors show the structure and mechanical properties (R_m, R_(p0.2), A_5, Z, KCU) of dual-phase steel with 0.09 percent and 1.90 percent Mn, that was obtain through intercritical quenching in oil in magnetic field and (for comparison) in, oil.
