## Description

- description: It has been reported that severely cold worked Fe-24.6Ni-5.8Al-0.4C
    (wt.%) had a yield strength of 2 GPa and a fracture elongation of 20 %, in which
    huge amount of Lüders-type deformation was observed. In the present article, we
    summarize the reports for high-strength Fe-Ni-Al-C, Fe-Mn, Fe-Cr-Ni base steels
    with the Lüders-type deformation so far, and provide our latest data on the effects
    of alloying elements and the cold-rolling reduction on the microstructure and
    mechanical properties of cold-rolled Fe-Ni-Al-C alloys. Previous reports imply
    that the phase stability of gamma phase affects the size of Lüders elongation,
    while the strategies to control the microstructure to achieve high strength and
    high ductility are currently unknown. Our latest study also shows that the gamma-phase
    stability affects the Lüders strain. In addition, it is confirmed that severe
    cold rolling by 80 % enables the prolonged Lüders strain as much as 25 % in nominal
    strain. This prolonged Lüders strain is achieved by multiple propagation of Lüders-type
    bands.
