“…It is found Si can inhibit the fragmentation and spheroidization of cementite lamellae and reduce the pearlite lamellar spacing. [3,10] Mn, Cr, and Nb can stabilize austenite structure and refine the lamellar spacing. [11][12][13] Additionally, numerous studies have shown that adding rare earth (RE) element in steel can also play an important role in steel microstructure and mechanical property optimization.…”

The effects of rare earth (RE) on the microstructure and mechanical properties of a pearlitic steel wire rod have been investigated under the dual low‐oxygen condition. The results show that the wire rods with different RE contents all have pearlite microstructure. As RE content increases from 0 to 310 ppm, the pearlite substructures such as interlamellar spacing, pearlite colony size and ferrite grain size decreasing remarkably, indicating that the nucleation and growth behavior of pearlite have changed. This is attributed to the combined effects of stimulating nucleation by large number of micrometer scale RE‐containing inclusions and decreased carbon diffusion due to RE in solution. As a results, the changes in microstructure lead to simultaneous enhancement of strength, plasticity, impact toughness and microhardness of pearlite wire rod, demonstrating that adding appropriate content of RE under the dual low‐oxygen condition is an effective alloying method to optimize the microstructure and mechanical properties of pearlitic steel wire rod.This article is protected by copyright.
