“…For example, when the solid sample is homogeneous, then it only needs polishing to be ready for analysis. 56 In this experimental work, micro-alloyed PM steels were analysed using the XRF technique to determine their elemental compositions. The chemical composition in % of mass fractions of Alloy 4 (Fe-0.25C-0.1Nb-0.1Al) are presented in Table 5.…”

In this work, the effects of the addition of Nb and Al on the microstructures and tensile behaviours of micro-alloyed powder metallurgy (PM) steels were investigated. The microstructure of the micro-alloyed PM steels was examined by light microscope, SEM, XRD, XRF and EDS. The results indicated that the addition of (0.1, 0.15 or 0.2) % of Nb-Al increases the yield strength (YS) and the ultimate tensile strength (UTS) of the PM sintered steels. Elongation also tends to improve with an increasing Nb and Al content. In addition, the Nb and Al limit the grain growth during austenitization. Keywords: powder metallurgy, micro-alloyed steels, microstructure V delu je bil preiskovan vpliv dodatka Nb in Al na mikrostrukturo in na natezno trdnost mikrolegiranih PM jekel, izdelanih iz prahov. Mikrostruktura mikrolegiranih PM jekel je bila preiskovana s svetlobnim mikroskopom ter s SEM, XRD, XRF in EDS. Rezultati so pokazali, da dodatek (0,1, 0,15 ali 0,2) % Nb-Al pove~a mejo plasti~nosti (YS) in natezno trdnost (UTS) sintranih PM jekel. Tudi raztezek se izbolj{a s pove~ano vsebnostjo Nb in Al. Ugotovljeno je {e, da dodatek Nb in Al omejuje rast zrn med avstenitizacijo.

“…The quantitative measurements of metal composition are very important in modern industry. To improve the performance of multielement analysis of metal samples, many approaches have been used in analytical laboratories, such as inductively coupled plasma, 1‐3 and X‐ray fluorescence 4 . However, most of these methods require complex and time‐consuming sample pretreatment process.…”

An efficient method has been developed to analyze metal species by using laser‐induced breakdown spectroscopy (LIBS). A least squares support vector machine (LSSVM) was applied to quantitative analysis of multimetal samples with different matrix content, as LSSVM can select the input variables and convert the mapping to the feature space to obtain the linear performance. In this work, three kinds of metal species (alloy steel, ferrochromium alloy, and ferromanganese alloy) were used to construct the LSSVM model. The correlation coefficients (R2), the root‐mean‐square error of prediction (RMSEP), and the average relative error (ARE) were calculated according to the estimated concentrations of chromium (Cr), manganese (Mn), titanium (Ti), and molubdenum (Mo) using the LSSVM model. The results showed that RMSEP decreased from 1.7047%, 1.3453%, 1.9253%, and 2.9431% to 0.0747%, 0.0942%, 0.0192%, and 0.0809%. The ARE of Cr, Mn, Ti, and Mo decreased from 10.2370, 9.8276%, 13.2460%, and 16.2386% to 1.0179%, 1.3937%, 2.1228%, and 1.6257%, respectively. This study demonstrated that LSSVM is an effective algorithm to improve both the accuracy and stability for metal analysis using LIBS.

“…In recent years the need for fast determination of precious alloys composition stimulated the proposals of different alternative techniques for caratage determination, among which the X-Ray fluorescence spectrometers are worth mentioning [8]. In this paper, both OES and XRF techniques will be compared on the basis of principle and applications with respect to ferrous and non-ferrous alloys.…”

Electrical spark-optical emission spectroscopy (OES) has been used for over 50 years for the direct analysis of alloys in the steel industry. This method has undergone continual improvement over time, but conventional OES can barely reach the new specification limits required for some critical steel alloys. As part of a continuous improvement process, instrument manufacturers, academic and industrial researchers are now showing a particular interest for x-ray spectroscopy (XRF) as an alternate and/or complementary approach for the analysis of steel alloys, mainly precious metals. In this work, by using the same optical mounting (i.e. same spectrometer model with the same spectral lines), we have directly compared the analytical performances of these two sources. By comparing the calculated concentrations obtained with these two sources using the same samples and the same standards, we show that in general the two sources give comparable quantitative results for major, minor and trace elements. The precision obtained with XRF is improved by a factor of two when compared to traditional spark Optical Emission Spectrometer. The results obtained in this work establish OES as a potential method for the quantitative analysis of steel alloys in different industries.
