摘要

试验钢由50 kg真空感应炉冶炼

锻造成60 mm板坯经1 250℃均匀化处理后热轧至4 mm板

再冷轧至1 mm板。研究了试验TRIP(转变诱发塑性)钢冷轧板820℃3 min淬火时等温淬火温度(350~450℃)和保温时间(1~10 min)对钢的组织性能的影响。结果表明

奥氏体等温淬火工艺对试验钢的力学性能有显著影响;最佳的等温淬火工艺为820℃3 min+400℃5min水冷

该钢的抗拉强度与总伸长率分别为766 MPa与37%

即强塑积达28.34 GPa·%;10 nm级Nb(CN)粒子的大量析出是造成该试验钢强度显著提高的主要原因。

Abstract

Test steel is melted by a 50 kg vacuum induction furnace

forged to 60 mm slab

homogenized at 1 250 ℃ then hot-rolled to 4 mm plate and cold rolled to 1 mm sheet. The effect of austempering temperature (350 ~ 450 °C) and holding time (1 ~ 10 min) on structure and mechanical properties of 820℃ 3 min quenched test TRIP steel cold-rolled sheet has been studied. Results show that the effect of process of austempering on mechanical properties of test steel is obvious； the optimum austempering process is 820℃ 3 min +400℃ 5 min

water cooling

the tensile strength and total elongation are respectively 766 MPa and 37%

i. e. the strength-plasticity product is 28. 34 GPa

% ； a lot of Nb (CN) particles precipitation with 10 nanometer size is main factor to increase the strength of test steel.
