metallographic analysis
metallographic techniques

The effect of solidification rate on the solidified structure , cooperation growth zone and microstructures such as tac rods volume fraction , tac rods average spacing , tac average transverse area and y phase in this eutectic composite were systematically investigated with lmc . the relationship between solidification processing controlling and solidification microstructure was established
借助金相技术、电镜技术、图象处理技术等多种分析测试手段，考察试样的界面形态、组织特征以及共晶形貌等多方面的凝固特性，建立了凝固过程控制与凝固组织的对应关系。
Therefore , in this paper , two directional solidification methods , czochralski method and electron - beam floating zone melting method , were used to obtain such material . the directional solidifition microstructures of si - tasi2 system was performed using neophot - 1 , amray - 100b sem and jem - 2000cx tem analysis technique
本文采用切克拉斯基法( cz法)和电子束区熔法( ebfzm )两种定向凝固方法制备该共晶自生复合材料；借助金相技术、电镜技术、图象处理技术等多种分析测试手段，考察了si - tasi _ 2共晶定向凝固组织和及其相应的工艺规范。
