The Influence of Quenching Temperature on the Mechanical Properties of a Dual-Phase Steel with 0.094% C and 0.53% Mn

Abstract:

In this article, the authors have analysed the influence of quenching temperature (T_Q) on the mechanical properties of a dual-phase steel with 0.094 % C and 0.53% Mn. In order to obtain a ferrite-martensite structure, specimens of this material have been the subjected to intercritical quenching that consisted of heating at 750, 770, 790, 810 and 830 ^°C, maintaining for 30 minutes and cooling in water. These specimens have then been subjected to metallographic analysis and tensile test in order to determine the volume fraction of martensite (V_M) in the structure, ultimate tensile strength (R_m), the 0.2% offset yield strength (R_p0.2), the total elongation (A₅) and the R_p0.2/R_m ratio.
