Quasiconvexity at the boundary and the nucleation of austenite [PDF]
Archive for Rational Mechanics and Analysis, 2014 Motivated by experimental observations of H. Seiner et al., we study the nucleation of austenite in a single crystal of a CuAlNi shape-memory alloy stabilized as a single variant of martensite. In the experiments the nucleation process was induced by localized heating and it was observed that, regardless of where the localized heating was applied, the ...

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 ...

THE CALCULATION OF STRESS INTENSITY FACTOR STEEL OF RAILWAY WHEELS [PDF]
Scientific Journal of Silesian University of Technology. Series Transport, 2020 From an analysis of the dependence complex of carbon steel properties on structural parameters, it was found that for an isostructural state, the influence of austenite grain size on impact strength exceeds the dependence on carbon content.
