“…This is why some thermo-(chemical) treatments, often coupled with additional surfaces treatments, have been developed in order to improve the general mechanical resistance of these materials together with their tribological properties. Among them, two main types of treatments are widely used, namely: -Classical heat treatments, such as age hardening [1], also known as precipitation hardening, which makes use of solid impurities or precipitates for the strengthening process. The alloy is aged by heat treatment, either at high or low temperature, so that precipitates can be formed.…”

The present paper investigates the microstructural features and associated hardening state of three different martensitic stainless steels (CX13, XD15 and MLX17 produced by Aubert&Duval), subjected to three different thermomechanical treatments, aimed at producing hard materials for tribological applications. It is thus shown that all treatments (cementation, HF quenching or Age Hardening) are efficient to produce hard surfaces. The bulk martensitic state is also studied. Although the three martensites look somewhat different, it is shown that the transformation always obeys the KS orientation relationship with some variant selection, which produces a significant amount of twin boundaries. These results are quite different from those found in low C steels. Based on a quantitative analysis of the EBSD microstructures, a quantification of the various relative hardening contributions (phase transformation, grain size, dislocation density, solid solution effect or precipitation) is then proposed.

The study investigates the possibility of applying induced plasma atomic emission spectrometry (ICP-OES) to determine silicon content exceeding 0.5% in iron-based samples. ICP-OES spectrometry requires liquid samples. Solid samples must be dissolved prior to the analysis. Dissolution of some types of steel requires strongly oxidising mixtures of inorganic acids. In such conditions, higher silicon contents tend to form insoluble oxides. Silicon oxides, in the form of amorphous sediment, precipitate on the bottom and walls of laboratory vessels. As a result, silicon determinations are strongly underestimated. The article presents the preparation of iron matrix based solutions for the determination of silicon-high concentrations using ICP-OES spectrometry.
