“…Also, not many differences are observed in the XRD patterns. These results are consistent with some of the recent studies on quenching and isothermal partitioning process, which have shown no significant changes in the retained austenite content, despite having a large variation in the grain size [7,8,10].…”

“…As mentioned in Table 2, similar to high strength, a higher hardness is achieved by the sample finish rolled at a lower temperature of 900°C. In the study of Haiko et al, on quenching and isothermal partitioning, an increase of about 20 HV has been reported for a decrease in the finish rolling temperature from 850 to 780°C [7]. The hardness and strength values have also been found to increase with reduced finish rolling temperature in direct quenched steels [34,35].…”

“…The quenching and isothermal partitioning process is an alternate way to relieve the brittleness of martensite by forming a mixture of low-carbon martensite and high-carbon retained austenite [3][4][5][6][7][8][9][10][11][12][13]. These two phases play their anticipated role, i.e.…”

“…Therefore, low-Si and Al-free steel has been chosen for the present study to eliminate the above-mentioned issues. The grain size of steel is an important parameter, which can have potential effects on martensitic phase transformation [7][8][9][10][33][34][35][36][37]. However, there is a lack of understanding of the grain size effect on the quenching and nonisothermal partitioning behaviour and ensuing mechanical properties.…”

The quenching and nonisothermal partitioning process has been found to achieve excellent combinations of strength and ductility through the retention of austenite in the microstructure. Therefore, in the present study, the effect of grain size on phase transformations and ensuing mechanical properties has been investigated. A low-Si and Al-free steel was finish rolled at different temperatures which was subsequently quenched to a constant temperature below M s for the formation of martensite with remaining untransformed austenite. This was followed by slow cooling to room temperature to simulate the condition of nonisothermal partitioning of carbon from martensite to the austenite. The results show that there is not much change in the average grain size with variation in the finish rolling temperature, as well as, no measurable differences are observed in the microstructural features and retained austenite content. The microstructure shows the presence of martensite, carbides, and a small amount of retained austenite. However, in terms of mechanical properties, the finish rolling at a lower temperature of 900°C lead to higher hardness and strength with comparable ductility in comparison to the sample which has been finish rolled at a relatively higher temperature (940°C). The above results will thus be helpful in designing the industrial processing schedule for low-Si steel to achieve enhanced performance.

The quenching and partitioning (Q&P) steels have shown to be promising candidates to be applied in fields where wear resistance is required. In this study, a medium and a high C steel are heat treated by Q&P and the resulting microstructure, hardness, and wear resistance are characterized. The mechanical stability of the austenite phase under wear test conditions is investigated. It is found that the stability of austenite is very high in the high C steel and decreases in the medium C steel. Additionally, the hardness and wear behavior of the Q&P‐treated steels are compared with the results obtained for quenching and tempering (Q&T) treated samples, showing that, although the hardness of Q&P steels is quite lower, the obtained wear rates are similar. It means that in the studied Q&P steels, although the austenite transformation into martensite does not occur considerably, the presence of austenite might play a key role in the wear resistance.

Metallurgical aspects of steels designed to resist abrasion, and impact-abrasion wear

Many abrasion resistant steels rely on a martensitic microstructure to ensure hardness, which in general correlates with better wear performance. However, in practice the steel may be subjected to a complex combination of conditions where hardness alone may not be sufficient to ensure tribological performance. This review is a critical assessment of the mechanical and metallurgical parameters that control wear resistance of steel in impact-abrasion conditions, although relevant work dealing with abrasion has also been included. It is found, for example, that fracture toughness and work-hardening behaviour have a role in enhancing the wear resistance of hard steels.
