Effect of aging treatment on mechanical property and h2s resistant behavior of acicular ferrite pipeline steels 时效处理对针状铁素体管线钢力学性能和抗硫化氢行为的影响
The microstructure of isothermally - quenched ductile iron ( adi ) is a mixture structure consisting of austenite plus acicular ferrite 摘要等温淬火球铁的显微组织由奥氏体加针状铁素体的混合组织组成。
C1o2 / tio2 granular composite the composite consists of acicular , conducting , ferromagnetic cro2 particles and spherical , insulating , diamagnetic tio2 particles 颗粒复合物这是针状、导电的磁性croz颗粒和粒径比ca12大得多的、球形且绝缘的非磁tio 。
Taurine , a kind of nonprotein aminophenol and white acicular crystal , smell - less , sourish and innoxious . it is widely consisted in organisms and also a aminophenol with special physiological function 为白色针状结晶、无臭、味微酸,溶于水,不溶于乙醇、乙醚和丙酮,无任何毒副作用。
So far as the grain size order of magnitude is concerned , the thickness of the acicular ferrite is about 200nm , while the thickness of the austenite existing inside the ferrite is only several nm to 10 nm 从晶粒尺寸数量级来说,针状铁素体的厚度约为200纳米,而铁索体内奥氏体的厚度仅为几到10纳米数量级。
