Work was done as a part of the project " New generation haulage system of highly productive longwall systems" aiming to develop and implement a new longwall shearer system called KOMTRACK. The widely used EICOTRACK feed system developed forty years ago is not adapted to modern longwall shearers' power. Within the project, an innovative, flexible feed system with a modular structure was created with the possibility of continuous adjustment to the carbon wall's unevenness. Newly-developed three cast steels variants have been initially selected to fabricate this system's elements. The material's final selection was realized based on the tensile tests, Charpy impact tests, Brinell hardness surveys, and wear resistance measurements. Results analysis allowed to select cast steel marked as "2", which fulfilled all requirements and was used in further casting trials.

“…To overcome this disadvantage, heat treatment has been adopted and proven to be an effective technology. Heat treatment is a kind of technology by conducting heating and cooling process to adjust the microstructure, and thus improve the needed mechanical properties and enhance the service life of components in engineering applications [9][10][11][12][13]. For nodular cast iron, heat treatment is a key process; not only can the matrix structure of nodular cast iron be adjusted by heat treatment to improve its performance, but also the nodulation of graphite and the distribution of alloying elements can be modified, and therefore, a much better comprehensive properties can be obtained [14,15].…”

The low-temperature impact toughness of nodular cast iron can be significantly enhanced by heat treatment, and thus meet the severe service requirements in the fields of high-speed rail and power generation, etc. In order to explore the enhancement mechanism, microstructure, hardness, composition and other characteristics of as-cast and heat-treated nodular cast iron is systematically tested and compared by optical microscopy, microhardness tester, EBSD, SEM, electron probe, and impact toughness testing machine in this study. The results show that heat treatment has little effect on the morphology and size of graphite in nodular cast iron, ignores the effect on the grain size, morphology, and distribution of ferritic matrix, and has little effect on the hardness and exchange of elements, while it is meaningful to find that heat treatment brings about significant decrease in high-angle grain boundaries (HAGB) between 59° and 60°, decreasing from 10% to 3%. Therefore, the significant enhancement of low-temperature impact toughness of nodular cast iron by heat treatment may result from the obvious decrease in HAGB between 59° and 60°, instead of other reasons. From this perspective, the study can provide novel ideas for optimizing the heat treatment process of nodular cast iron.

“…P. Wolfram et al [ 17 ] calculated the volume loss of Q&P‐treated 9260 steel with normalized samples with respect to the performance of AR400F samples during dry sand and rubber wheel (DSRW) wear tests, and here also a beneficial effect of austenite was confirmed. Wang et al [ 20 ] found that by applying a Q&P treatment to a ductile cast iron wear resistance was improved and that the employed partitioning time affected the obtained wear rate, first increasing with the increase of the partitioning time and then decreasing with a further time increasing. Lai et al [ 21 ] concluded that compared with Q&T treatment, wear resistance of a high C steel was improved by applying a series of Q&PT (quenching and partitioning‐tempering) treatments, which was associated with the formation of film‐like and blocky austenite during partitioning stage.…”

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.
