“…The prior austenite grain boundaries were revealed by etching the specimens for evaluated the mean grain size. Table 3 shows size distribution of austenite grain and Table 4, there is comparison between the mean austenite grain size of Spektor's method and the values of G, đ & l of International standard [10,[37][38][39][40]. The microalloyed steel was studied investigated to optimize the influence of single and multiple microalloying additions on the ferrite grain size microstructure in as-cast state.…”

“…A ferriticpearlitic microstructure with the predominant content of plastic ferrite is responsible for this combination of mechanical properties [1,2]. At the same time, these properties can be changed by increasing the Mn content to about 1.8% (solution strengthening) or by introducing micro-additives, such as V, Nb or Ti (structure refinement and strengthening with fine-dispersed particles of carbides and carbonitrides) [2][3][4][5][6][7][8][9].…”

The effect of vanadium microaddition on the strength of low-carbon cast steel containing 0.19% C used, among others, for castings of slag ladles was discussed. The tested cast steel was melted under laboratory conditions in a 30 kg capacity induction furnace. Mechanical tests were carried out at 700, 800 and 900°C using an Instron 5566 machine equipped with a heating oven of  2C stability. Non-standard 8fold samples with a measuring length of 26 mm and a diameter of 3 mm were used for the tests. It has been shown that, compared to cast steel without vanadium microaddition, the introduction of vanadium in an amount of 0.12% to unalloyed, low carbon cast steel had a beneficial effect on the microstructure and properties of this steel not only at ambient temperature but also at elevated temperatures when it promoted an increase in UTS and YS. The highest strength values were obtained in the tested cast steel at 700C with UTS and YS reaching the values of 193 MPa and 187.7 MPa, respectively, against 125 MPa and 82.8 MPa, respectively, obtained without the addition of vanadium. It was also found that with increasing test temperature, the values of UTS and YS were decreasing. The lowest values of UTS and YS obtained at 900°C were 72 MPa and 59.5 MPa, respectively, against 69 MPa and 32.5 MPa, respectively, obtained without the addition of vanadium.

“…The demands for producing high-hardness steel castings with high-impact toughness and wear resistance have encouraged some researchers to focus on the low-alloy cast steels. [5][6][7][8][9] However, the impact toughness of the low-alloy cast steels is low when the hardness is higher than 50 HRC. This is the main obstacle for the low-alloy cast steels to use in manufacturing industrial parts.…”

Two medium carbon low-alloy MnSiCrB cast steels containing different Cu contents (0.01 wt pct and 0.62 wt pct) were designed, and the effect of Cu on the mechanical properties and corrosion-abrasion wear behavior of the cast steels was studied. The results showed that the low-alloy MnSiCrB cast steels obtained excellent hardenability by a cheap alloying scheme. The microstructure of the MnSiCrB cast steels after water quenching from 1123 K (850°C) consists of lath martensite and retained austenite. After tempering at 503 K (230°C), carbides precipitated, and the hardness of the cast steels reached 51 to 52 HRC. The addition of Cu was detrimental to the ductility and impact toughness but was beneficial to the wear resistance in a corrosion-abrasion wear test. The MnSiCrB cast steel with Cu by the simple alloying scheme and heat treatment has the advantages of being high performance, low cost, and environmentally friendly. It is a potential, advanced wear-resistant cast steel for corrosion-abrasion wear conditions.
