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 ...

Austenite-Based Fe-Mn-Al-C Lightweight Steels: Research and Prospective
Metals, 2022 Fe-Mn-Al-C lightweight steels have been investigated intensely in the last a few years. There are basically four types of Fe-Mn-Al-C steels, ferritic, ferrite-based duplex/triplex (ferrite + austenite, ferrite + austenite + martensite), austenite-based ...

On carbon distribution in austenite Fe‑C alloys
Литьë и металлургия, 2022 Based on the calculations of the model of the elementary crystal cell γ‑iron, it is shown that carbon ions cannot be present in its open pores. Carbon in Fe‑C alloys dissolves and distributes mainly as elementary graphite nanocrystals. In steel austenite,
