Fig.5 shows stress–strain curves of the BM,NFSP,and SFSP samples at room temperature,and the tensile strength test results are summarized in Table 1.The ultimate tensile strengths(UTS)of the low-carbon steel increased significantly after NFSP and SFSP,while the elongation to failure(EL)decreased only slightly.The UTS and EL of the BM sample was 470 MPa and 51.4%,respectively.Compared with BM,the UTS of the NFSP and SFSP samples increased by 27.0%and 38.7%,respectively.The ELs of the NFSP and SFSP sample were 47.1%and 45.6%,respectively,which is slightly lower than that of the BM.
