测定了3CrMnMoVS钢过冷奥氏体连续冷却转变曲线(CCT曲线),并利用CCT曲线着重分析该钢在中等冷速(200—1000℃/h)下连续冷却后的光学和薄膜金相组织。结果表明,在冷却速度大于0.72℃/S条件下连续冷却,金相组织主要是板条马氏体。空冷条件下,其金相组织主要是中温转变产物:B粒+B上+B下的精细混合组织,且基体上弥散分布细小颗粒状VC

采用内氧化剂KClO3,在常压空气中自蔓延高温合成锰锌铁氧体粉料.粉料性能用XRD、SEM、VSM等表征,讨论了燃烧合成的影响因素.结果表明:当反应放热供氧系数m为0.54、反应控制放热系数k为0.6、燃烧合成速度为1.93mm·s-1、燃烧温度为1593K时,可制备性能优良的锰锌铁氧体粉料,其比饱和磁化强度为64.44A·m2·kg-1,比剩磁强度为1.349A·m2·kg-1,矫顽力为0.24kA·m-1,平均粒径为1.42μm

采用Gleeble 1500型热模拟试验机进行单轴压缩实验,研究了Fe3Al基合金在温度为850℃、应变速率为10-3s-1条件下的组织演变.结果表明:在本实验变形条件下,Fe3Al基合金能够发生动态再结晶.变形初期,Fe3Al可以通过晶界弓弯机制形成动态再结晶核心,即发生了不连续动态再结晶现象,但再结晶核心不易长大.随着应变量的增加,通过连续动态再结晶形成一定量的再结晶细小晶粒
