摘要

试验的Q & P(淬火和配分)钢(%:0.17C、1.40Si、1.48Mn、0.25Al)由7.5 kg真空感应炉冶炼

轧成1.0～1.5 mm钢板

采用井式盐浴炉模拟了试验Q & P钢的热处理工艺

经910℃奥氏体化

淬至200～245℃

20 s

升温至配分温度300～450℃

60～600 s

快冷。结果表明

采用淬火245℃ 20 s

配分300～350℃≥300 s可保证碳原子由马氏体向残留奥氏体富集

试验钢具有高的强塑积(25000～30000 MPa%)。

Abstract

Test Q & P(quenching and partitioning)steel(%:0. 17C

1.40Si

1.48Mn

0.25Al)was melted a 7.5 kg vacuum induction furnace then rolled to 1.0~1.5 mm plate.The heat treatment process of the test Q & P steel plate was simulated by a shaft salt bath furnace with austenizing at 910 ℃

quenching to 200~245 ℃ for 20 s

heating to parti-tioning temperature 300～450℃ for 60～600 s

then quick cooling.Results show that with quenching to 245℃ for 20 s

partitioning at 300～350℃ for ≥300 s

it is available to assure the carbon atom accumulating to residual austenite from martensite and get high product of strength-elongation(25000～30000 MPa%).
