A new method to calculate the plastic anisotropy r-values of austenitic and ferritic stainless steels has been developed. The mean orientation individual grains is obtained from SEM-EBSD data for are calculated by weighting all slip systems according their Schmid factors. Calculated measured in good agreement steels. However, steels, which highly anisotropic, requires introduction a factor thre...

In some austenitic stainless steel welds grains orientations cause deviation and splitting of the ultrasonic beam. It is especially true in the case of multipass welds when the remelting process after each pass causes complex solidification process. With the new model MINA (Modelling anisotropy from Notebook of Arc welding) we show that we are able to predict thoroughly grains orientations. Thi...

The objectives of the NGV (Next Generation Vehicle) Project were to demonstrate that stainless steel can be used to reduce weight and costs, and to improve safety and sustainability in structural automotive systems. The deliverables include enabling technologies, virtual technology for design and development, processing and testing. The compilation of the results as well as aspects such as new ...

This paper aims at the phase identification and quantification in transformation induced plasticity duplex stainless steel (TDSS) base weld metal containing ferrite, austenite, martensite. Light optical microscopy (LOM) electron backscatter diffraction (EBSD) analysis were employed to analyze phases. Samples either mechanically or electrolytically polished study effect of preparation technique....

Abstract High‐temperature corrosion was studied under multiple chemical loads on ferritic‐austenitic model alloys (Fe–13Cr, Fe–18Cr–12Ni, and Fe‐25Cr–20Ni) with KCl deposit 0.5% /99.5% Ar gas atmosphere at . Postexposure characterization done by X‐ray diffraction scanning electron microscopy. In a pure /Ar environment protective scale formed all samples. The introduction of deposits causes the ...
