“…Original position statistic distribution analysis (OPA) is a novel statistic characterization method for the quantitative distribution of different chemical composition and also can investigate their states of components on a large area of material. [7][8][9][10] Moreover it can be used for the determination of inclusions by collecting and discriminating the signals produced by single spark discharge in the way of no pre-sparking, scanning and emitting continuously. In this paper, the sulfides of some different gear steels were analyzed by original position statistic distribution analysis technique and the multielemental correlation on high intensity signals has been investigated in order to obtain the composition and proportion of different type of sulfides.…”

The sulfides in some different gear steels were analyzed by original position statistic distribution analysis technique. The relationship between the proportion of the frequency of high intensity signals and the content of total sulfur and total oxygen in samples has been investigated. Multi-elemental correlation on high intensity signals has been performed in order to obtain the composition and proportion of different type of sulfides. It was found that the proportion of simple sulfide was more than that of oxide-sulfide duplex inclusion in six gear steel samples. The ratio of the oxide-sulfide duplex inclusion to the total sulfides were determined by the present method and the results had good coincidence with the value obtained by quantitative metallographic method and scanning electronic microscopy. The influence of the content of Ca on the composition of the sulfides was investigated. It was found that the relative proportion of the complex inclusions of Al-Ca-Mn-O-S increase with the rise of the content of Ca in gear steels. The ratio of the content of Ca to the content of S (Ca/S) also had great effect on the relative proportion of the oxide-sulfide duplex inclusion.

“…Several studies have addressed transient phenomena during continuous casting. A study by Zhang et al 1) described the influence of casting variation on nonmetallic inclusions in interstitial free steel slabs, indicating that more inclusions entrapped during periods of casting speed variation. Liu et al 2) reported that the cleanliness of steel remains constant during steady state over multiple sequences based on the same operation parameters, whereas changes significantly during the transient stages, as shown in Fig.…”

Using the CALPHAD technique, an assessment of the binary EuCl 3 -MgCl 2 and EuCl 3 -BaCl 2 systems has been carried out in this study. The modified quasi-chemical model was defined to describe the Gibbs energies of the liquid phases, and the model parameters were optimized from the experimental phase diagram data. The phase diagrams and enthalpies of mixing of the EuCl 3 -MgCl 2 and EuCl 3 -BaCl 2 systems were calculated. The calculated results by the present method agree well with the experimental data. The Gibbs energies of formation of Mg Cl 13 from the pure components were predicted.
