摘要：The microstructure, mechanical properties, and abrasion resistance of an Fe-2wt%B-0.35wt%C alloy with various Ni contents were analyzed. As the Ni addition increases, the Ni content of the matrix and M2B (M indicates Fe, Cr, and Mn) increases linearly with the relationships of y = 0.992x and y = 0.224x, respectively. With the Ni content increasing from 0 wt% to 1.2 wt%, the critical cooling rate of the alloy changes from 0.5 degrees C/s to 0.1 degrees C/s, which decreases the volume fraction of as-cast pearlite from 72.86 vol% to 3.49 vol%. Moreover, the Ni atom replacement is helpful in the formation of edge dislocation in the M2B, facilitating an increase in the toughness characteristic delta(A) of M2B from 2.85 to 3.04. Interestingly, when the Ni content is less than 0.9 wt%, the heat treatment makes a huge contribution to the macrohardness, bending stress, and abrasion resistance of alloy, owing to the formation of martensite. However, once the Ni content exceeds 0.9 wt%, heat treatment plays a negative role in the macrohardness, bending stress, and abrasion resistance of the alloy, because of the precipitation of M-23(B,C)(6).
