摘要

研究了终锻温度810～960℃和锻压比3～6对贝氏体钢(%:0.16C、0.91Si、1.98Mn、1.03Cr、0.17Mo、0.065V、0.001Ti)铁素体析出的影响。结果表明

贝氏体钢锻造过程中的变形提高了钢中奥氏体至铁素体相变的临界温度;在终锻温度为810～820℃时

钢中产生变形诱导铁素体相变

当锻压比由3增至6时

铁素体的体积分数由1.8%增至9.6%

铁素体由针状趋于演变为块状;终锻温度为940～960℃时

钢中铁素体主要为针状

随着锻压比由3增至6

钢中铁素体体积分数由3.0%降至0.6%。

Abstract

Influence of finishing temperature 810 ~960 ℃ and forging ratio 3 -6 on precipitation of ferrite in bainitic steel-0. 16C

0.91 Si

1.98Mnt 1.03Cr

0. 17Mo

0. 065V

0. 001 Ti has been studied. Results showed that the critical temperature of phase transformation for austenite to ferrite increased by deformation of the bainitic steel during forging； with forging finishing at 810 ~ 820 ℃. the defbnnation induced ferrite precipitation occurred in steel and with increasing forging ratio from 3 to 6

the volume fraction of ferrite in steel increased from 1. 8% to 9. 6% accompanied acic ular ferrite evolving to massive ferrite； and with forging finishing at 940 -960 °C

most of ferrite in steel was acicular

with increasing forging ratio from 3 to 6 the volume fraction of ferrite in steel dec revised from 3. 0% to 0. 6% .
