并用光学显微镜和透射电镜研究了不同的终轧温度、冷却速度下的组织和相变。结果表明

冷速为1℃/s时

弹簧钢60Si2CrVAT中的珠光体含量约为98%;随着冷速的增加

铁素体和珠光体的含量逐渐减小

贝氏体和马氏体含量逐渐增加;当冷速达到9℃/s时

基体全部为马氏体;终轧温度850℃、冷速为1℃/s时

弹簧钢60Si2CrVAT的索氏体含量达到90%

强塑性最好

Abstract

The continuous cooling transformation(CCT)curves

structure and phase transformation of quality spring steel 60Si2CrVAT with different finishing rolling temperature and cooling rate have been examined and studied by Gleeble-1500 thermal mechanical simulator

optical microscope and transmission electron microsope. Results showed that as cooling rate was1 ℃/s

the pearlite content in spring steel 60Si2CrVAT was about 98%;with increasing cooling rate the ferite and pearlite content gradually decreased while bainite and martensite content increased; and as cooling rate was up to 9 ℃/g

the matrix was all martensite.With finishing temperature 850 ℃ and cooling rate 1 ℃/s

the sorbite content in spring steel 60Si2CrVAT was up to90% with excellent strength and toughness i.e. R

1301 MPa

p0.2

928 Mpa

A23.8% and Z38.6%.
