“…As the intercritical annealing temperature increases, the amount of martensite increases up to 90% after water quenching. Bidmeshki et al studied the dual-phase formation of St52 steel is used in this study by applying 780°C intercritical annealing for 30 minutes and the martensite fraction was calculated as 53% [16]. In this work, the martensite fraction was calculated as 54% by applying 780°C intercritical annealing.…”

Dual phase (DP) steels are rapidly becoming more and more popular for automotive applications. They offer a weight reduction with a combination of energy absorption for crash zones. Rails, reinforcements, back panels, cross members, and pillars can be given as application examples. DP steels microstructure consists of a soft ferrite matrix with hard martensite islands. The hard martensite islands provide strength while the ductile ferrite provides formability. The strength level of DP steel is related to the amount of martensite in the microstructure, and the martensite amount can be arranged via intercritical annealing. In this work, thermodynamic analysis of St52 steel was carried out with Thermo-Calc software. A1 and A3 temperatures were determined by calculating the temperature-dependent phase fractions. Intercritical annealing temperatures were determined according to the calculated critical temperatures (A1 and A3). The intercritical annealing process was modelled by using Simheat NxT software. In this modelling and simulation work, the effect of intercritical annealing temperature on the final microstructure and hardness of DP steel was investigated.

“…However, the improvement of material strength and hardness often sacrifices toughness, which may lead to brittle spalling of the material surface, thereby deteriorating the wear performance. The use of high manganese steels (TWIP steels) [15][16][17][18] and dual-phase steel wear parts [19][20][21][22] can improve the toughness and spalling resistance of the material surface, but their low initial hardness and strength cause the material to easily undergo plastic deformation, which limits their development.…”

This study aims to revealing the relationship among retained austenite (RA) morphology, deformation‐induced transformation (DIPT) behavior, and surface wear behavior. The hardening and fatigue behavior during wear of continuous film‐like RA (CFRA), blocky RA (BRA), discontinuous film‐like RA (DFRA), and point or flocculent RA (PRA) achieved through different tempering processes was investigated using quasi‐in situ fatigue test and impact abrasive wear test. RA morphology exhibited a significant influence on hardening and fatigue behavior during wear. CFRA exhibited the best wear properties, owing to its excellent fatigue performance and hardening capacity. The BRA displayed relative high wear performance, with adequate hardening capacity but weak fatigue performance. DFRA demonstrated comparable wear resistance to BRA because of better fatigue performance. PRA exhibited deficient wear performance because of insufficient fatigue properties and low work‐hardening ability.

In this paper, the effects of different quenching temperatures on the microstructure and properties of Fe–4.0C–35.0Cr–0.5Si (wt.%) low-silicon hypereutectic high-chromium cast iron (LS-HHCCI) was investigated. The effect of quenching temperature on the microstructure of LS-HHCCI was analyzed by optical microscope, scanning electron microscope, and X-ray diffractometer. After quenching at different temperatures, the hardness and wear resistance of LS-HHCCI were tested by Rockwell hardness tester, microhardness tester, and wear testing machine. The results show that the microstructure of as-cast LS-HHCCI is mainly composed of austenite matrix and M7C3 carbides. After quenching, the austenite matrix is transformed into martensite, and M23C6 type secondary carbides are precipitated in the matrix. As the quenching temperature increased from 950 °C to 1100 °C, the eutectic carbides first appeared as fine needles, and then they gather and grow up, showing elongated or lumpy. The hardness and abrasion resistance first increase and then decrease, it reached peak values of 67.2 HRC at the temperature of 1050 °C, while the wear resistance is the best.
