Graphite and Solid Fraction Evolutions during Solidification of Nodular Cast Irons
Metals, 2015 Ductile iron casting production is strongly affected by austenite and graphite distribution obtained after the solidification process. At the same time it is accepted that solidification behavior can be considered as hypo-, hyper- or eutectic depending ...

INFLUENCE HOT PLASTIC DEFORMATION ON THE STRUCTURE AND PROPERTIES OF CARBON STEEL OF THE RAILWAY WHEEL [PDF]
Scientific Journal of Silesian University of Technology. Series Transport, 2023 The study is devoted to the explanation of the influence of hot plastic deformation on the properties of railway wheels. The shape of individual elements of the wheel provides for a different degree of hot compression, which determines the mechanism for ...

Materials and Corrosion, Volume 73, Issue 12, Page 1979-2003, December 2022., 2022 High‐temperature corrosion in reducing HCl and H2S‐containing atmospheres is challenging for commercially used alloys as several corrosive agents in the atmosphere show various different reactivities with the numerous alloying elements at different temperatures. Thus, the prediction of corrosion mechanisms in such environments is challenging.

In-Situ Neutron Diffraction and Crystal Plasticity Finite Element Modeling to study the Kinematic Stability of Retained Austenite in Bearing Steels [PDF]
Materials Science and Engineering A 711 (2018) 579-587, 2018 This work integrates in-situ neutron diffraction and crystal plasticity finite element modeling to study the kinematic stability of retained austenite in high carbon bearing steels. The presence of a kinematically metastable retained austenite in bearing steels can significantly affect the macro-mechanical and micro-mechanical material response ...

Materials and Corrosion, Volume 74, Issue 1, Page 79-90, January 2023., 2023 The oxidation behavior of FeCoCrNiMn‐based high‐entropy alloys was evaluated at 600–800°C for 100–500 h of exposure to synthetic air. Substitution of Mn by Cu led to significantly enhanced oxidation resistance, which could be further improved by the addition of Al.

Cyclic Re-austenitization of Copper-bearing High-Strength Low-Alloy Steels Fabricated by Laser Powder Bed Fusion [PDF]
, 2020 For the first time, cyclic re-austenitization is carried out for additively manufactured high-strength low-alloy (HSLA) steels in order to refine the microstructure by reducing the prior austenite grain (PAG) size. In this work, HSLA-100 steels processed using laser powder bed fusion (LPBF) technique are subjected to several cycles of re ...
