In the process of wollastonite fining , we can forge and then cool it to protect its crystal structure which is short acicular fiber . mechanochemical modification by jet mill is super to speedily mixed modification by stirring mix 硅灰石微粉碎过程中,为保护硅灰石的短纤维针状结构,可在粉碎前对硅灰石进行煅烧空冷处理。
Influenced by the alternating current field , except that a little of eutectic iron - phase still is the acicular structure , the most of eutectic iron - phase of the al - 20si - 5fe - mn alloy is refined into tiny particles which is segregated Al - 20si - 5fe - xti合金通过交流电场作用,共晶组织全部呈细小的颗粒状均匀分布于- al基体上。
The thesis was originally intended to reveal magnetoresistance effect in two kinds of novel composites : ( 1 ) acicular cro2 / spherical insulating granular composite ; ( 2 ) cro2 granules coated with insulating polymer , respectively 本论文的目的是研究两类复合材料:针形cro _ 2和球形绝缘颗粒复合型;聚合物包裹cro _ 2颗粒型。
Its austenite has two types of morphologies : one type is the austenite which is existing between the acicular ferrite and has approximately equiaxial block shape ; another type is the austenite which is existing inside the acicular ferrite and has thin slice shape 其奥氏体有两种形态:一种是存在于针状铁素体之间的近似于等轴形的块状奥氏体;一种是存在于针状铁素体之内的薄片形奥氏体。
Acicular - fe2o3 and ? feooh nano particles are prepared by hydrolytic method and ? feooh with good axial ratio is prepared by microwave - induced method , then 30 % cobalt is doped into this ? feooh sample . ideal acicular ferrite samples have been prepared and the formation mechanism has also been studied Feooh ,并对其进行掺30 %钴的实验条件的摸索,制备出了较理想的针形的铁氧体粒子,对该粒子的生长机理进行了分析。
