V-Ti微合金钢的组织性能及相间析出行为*
DOI: 10.3724/SP.J.1037.2013.00681, PP. 524-530

Abstract:
采用热模拟实验研究了等温温度对V-Ti微合金钢组织性能及相间析出行为的影响规律,利用OM和TEM分析了不同等温温度下实验钢的组织特征.结果表明,不同等温温度下均可得到大量铁素体组织,随等温温度的降低,铁素体体积分数增加,铁素体晶粒尺寸减小.不同等温温度下均可观察到平面相间析出,且降低等温温度可显著细化相间析出列间距和析出粒子尺寸.纳米碳化物具有NaCl型晶体结构,晶格常数约为0.436nm,同铁素体基体满足(100)carbide//(100)ferrite和[011]carbide//[001]ferrite的B-N关系.在680℃下等温30min,沉淀强化量可达到360.6MPa.
