    Effect of Heat Treatment Process on the Section Shrinkage of 1Cr16Ni2MoN Blade Steel by Zhang Xiuli, Gong Zhihua, Liu Xinquan, Sun Guoyang, Ma Yuanyuan, Gao Xiang

    Published 2025-08-01
    “…With the increase of tempering temperature, the amount of carbide precipitation increases, and the carbide at grain boundary and Flat noodles boundary gathers and coarsens, which leads to the decrease of the bonding force between flat noodles and phase interface, which can accelerate the generation and propagation of cracks, thus reducing the reduction of area and impact toughness.Taking into account the control of δ - ferrite and cross-sectional shrinkage rate, it is necessary to adjust the composition, the content of C should be minimized as much as possible, with the carbon content maintained at 0.15%, the content of N should be suitably increased to upper limit of 0.007%, and the diffusion annealing process should be implemented to reduce the enrichment of carbides resulting from segregation.…”
