In region of columnar grain, preferred orientation growth is obvious. Obviously preferred orientation on 〈001〉 was confirmed by the antipole figure. Besides, the CSL grain boundary such as ∑3,∑5 and so on are observed. Among these kinds of boundaries, the ∑3 boundary has the highest frequency.

测试结果表明：CVDW生长组织具有三个生长区，分别是等轴晶区、混合生长晶区和柱状晶区；柱状晶区的晶粒具有显著的〈001〉择优生长；低∑CSL晶界占据较大比例，其中以∑3、∑5为主要结构，∑3的出现频率最大。

在低强度电磁振荡条件下，凝固组织细化和等轴晶化的原因是：电磁振荡力对金属初生晶的周期性拉伸、压缩、剪切、折弯、扭转等机械作用，使其出现断裂和剥落，增加形核数量；电磁振荡的局部搅拌作用使固/液界面前沿的温度和成分趋于均匀化，导致梯度降低，抑制了柱状晶的生长。

The intensity of pressure is the most markable factor that influence the casts mechanical properties and microstructure. When its value exceeds 40MPa, the disfigurement such as shrinkage porosity can be effectively reduced . when its value exceeds 120MPa, the pressure obviously influence the crystal performances of liquid metal also, and compact homogeneous exiguous equiaxial crystal can be obtained. Pressure can also increase the solubility of Cu in a -Al.

比压是对铸件力学性能和显微组织最为显著的因素，其取值超过40MPa时，能有效减少缩松等缺陷，当比压超过120MPa时，除了能减轻铸造缺陷外，还对液态金属的结晶性能产生显著影响，在铸件断面上得到致密、细小且均匀的等轴晶。

Moreover, its microstructural characters possess several configurations under TEM, which are (1) ferrite laths with obvious interface,(2) ferrite laths without obvious interface, but the interface can be discerned faintly from the linear arrangment of those directional islands,(3) the coexistence of ferrite laths and non--equiaxed grains. These are somewhat different from those of weld structures, which are generally thought to consist of an assemblage of interwoven ferrite laths.

可能主客观原因都是很多的，但是，我国数控机床功能部件的发展落后──品种少，单元技术水平低，性能质量不够稳定，成本居高不下，交货不够及时等──满足不了数控机床主机产品发展的需要，不能不说是最直接、最主要的原因，因为所有的数控机床都是由各种功能部件（包括主轴头、直线滚动导轨、滚珠丝杠副、数控刀架、刀库机械手、回转工作台、数控伺服系统、测量反馈以及安全防护装置等）在床身、立柱等基础机架上集装而成的，功能部件是数控机床的重要组成部份，而且是不可或缺的部份。
