本文選題：容器鋼　切入點(diǎn)：奧氏體晶粒尺寸　出處：《鋼鐵研究學(xué)報(bào)》2016年02期

【摘要】：利用光學(xué)顯微鏡等研究了SA516Gr60N容器鋼在不同奧氏體化溫度下奧氏體晶粒尺寸的長(zhǎng)大規(guī)律以及微合金元素Nb、Ti、V的固溶規(guī)律。研究結(jié)果表明,隨著奧氏體化溫度的升高,微合金元素Nb、Ti、V的固溶量逐漸增加;990~1 050℃時(shí),原始奧氏體晶粒尺寸增加緩慢,晶粒細(xì)小均勻;1 070℃時(shí)晶粒出現(xiàn)異常長(zhǎng)大現(xiàn)象,隨后部分奧氏體晶粒急劇長(zhǎng)大,不均勻性越來(lái)越明顯;1 170~1 210℃時(shí),奧氏體晶粒尺寸均勻化。
[Abstract]:The growth rule of austenite grain size at different austenitizing temperatures and the solid solution law of microalloying element NbTiTI-V in SA516Gr60N container steel were studied by means of optical microscope.The results show that with the increase of austenitizing temperature, the solution content of NbTiOV increases gradually at 990 鈩，
