摘要
Abstract
Four types of C & Mn steels were researched ,microstructure and mechanical properties were studied after the same rolling and quenching processes ,and the microstructures were characterized by both optic microscopy and transmission electron microscopy .T he result show s that w hen the C content is 0 .21% ,and the Mn content ranges from 1 .5% to 1 .9% ,the yield strength of the tested steels is 1145 MPa to 1171 MPa ,the tensile strength is 1270 MPa to 1304 MPa .And the elongation is greater than 3 .05% ,after heating to 860 ℃ and maintaining 600 s and then quenching in water ,and tempering at 350℃ for 600 s .It is shown that the microstructures were lath martensite after quenching process ,and a large number of carbides were precipitated inside the lath martensite and along the grain boundary .关键词
