退火温度对Nb+Ti双稳铁素体不锈钢织构的影响颜海涛1,2,毕洪运2,李鑫2,顾佳卿2,徐洲-2(1.上海市上海交通大学材料科学与工程学院2.上海市宝钢股份研究院)摘 要:利用电子背散射衍射技术(EBSD)研究了不同退火温度对Nb+Ti双稳铁素体不锈钢织构的影响.结果表明,随着退火温度的升高,α织构逐渐减弱,γ织构逐渐增强,当退火温度为920℃时,α织构基本消失,材料以γ织构为主.对再结晶织构的形成机制的探讨认为,铁素体不锈钢具有较强的γ织构归因于"定向形核"和"选择生长"共同作用的结果. 关键词......
and texture change after uniaxial compression at 430 °C of an extruded AZ31 alloy were studied. The samples were loaded following two routes insuring two initial textures of the samples ... by: with an n value of around 15. The annealing texture with grown grains is a retained hot deformation texture without emerging or strengthening other components. Abnormal grain growth......

of physical and mechanical characteristics of rocks is very important issue in various geotechnical projects. The characteristics are mainly influenced by the microfabric-texture features of rocks. In this research, dry unit weight, effective porosity, point load index, Schmidt rebound hardness, uniaxial compressive strength, and texture coefficient were measured with the aim of correlating......
