摘要: Four low-carbon bainitic steels with different nickel (Ni) and chromium (Cr) contents were designed to analyze the influences of Ni Cr on transformation, microstructure properties by metallographic method dilatometry. The results showed that compared base steel, kinetics transformation in or addition was retarded. In addition, single increased amount spite retarded kinetics, while decreased transformation. Combined further reduced Moreover, individual composite improved strength refining bainite microstructure, carbide precipitation martensite, but total elongation at same time. Steel presented best product elongation. work provided reference for composition design steels.
