eutectic structure

The percentage elongation is affected mainly by the morphology of eutectic structure;

伸长率主要受共晶组织形态影响；

Appreciation of Crystal On the Mechanism of Eutectic Structure

Eutectic Structure of Binary Mg Li Alloy During Directional Solidification

定向凝固条件下二元Mg-Li合金共晶组织的研究

For the unmodified eutectic silicon, the large cooling rate can promote the transition of eutectic silicon from a coarse plate to a fibrous structure, resulting in modification.

即使对于未变质合金，大的冷却速度仍可以实现共晶硅由粗大的片层状向纤维状分枝结构转变，产生变质作用。

Investigation on the pseudo eutectic structure formed by solid diffusion of Zn powder and Al powder

Zn粉和Al粉固相扩散形成共晶类组织的研究

When the pulling rates was low as 1 mm/ min, three-phase eutectic structure was observed and characteristic of directional solidification could be found in longitudinal section.

当下拉速率为1mm/min时，合金组织呈现三相共晶结构，纵截面有定向凝固趋势。

At the same time, the addition of aluminum to obtain another eutectic structure which is fine and disperse.

与此同时，铝的加入，获得了细密、弥散的另一共晶组织。

Study shows that quenched boron eutectic structure possesses the excellent wear abrasion property.

研究表明：硼共晶组织经淬火后，具有优良的抗磨粒磨损性能。

Under the conditions of containerless processing, Pb-4wt% Sn-12wt% Sb ternary eutectic alloys exhibit a transition from lamellasome structure to granular structure;

在落管无容器快速凝固条件下，Pb-4wt%Sn-12wt%Sb三元共晶合金组织形态由层片状转变为粒状；

To break down the eutectic carbide network of A-cast structure with grain size 4-5 grade, tensile strain of 60% is needed.

当铸志晶粒度力4～5级寸，破碎晶炭化物组织需要有60%以上的拉应变。
