Thermomechanical histories
Webb19 feb. 2024 · Hot plastic working behavior and microstructure evolution were investigated during a production process of four medium-Mn steels, which differed in Mn (3 and 5%) and Nb contents. The production process started with casting, followed by hot forging, rough hot-rolling and concluded with final thermomechanical processing, which was … Webb5 feb. 2024 · The creep data in Figs. 3 and 4 were divided into four processing histories: cold-worked (CW), cold-worked and stress-relieved (CWSR), annealed, and unspecified. As can be seen in Fig. 3 (Zircaloy-2), the data measured for all four processing histories appear to obey similar trends.
