| 1. | The effect of solidification rate on eutectic microstructure of high chromium cast iron
凝固速度对高铬铸铁共晶组织的影响 |
| 2. | L4in this eutectic composite . the volume fraction of tac could be changed with increasing solidification rate
随着凝固速率的增大， '相的尺寸越来越小，其形状也越来越圆。 |
| 3. | The former followed linearity rule and the latter followed the rule of r - 0 . 5 the volume fraction was steadiness when the solidification rate increased
随凝固速率的增加tasi _ 2纤维体积分数基本不变。 |
| 4. | Following the increase of the solidification rate , the y ? phase gets smaller and smaller , and the morphology of y ? phase becomes more circular . the inter - rod spacing of tac obeys relationship with x13 . 18r04972 , and the transverse area of tac versus solidification rate is s = ? . 6597r + 5
在该共晶自生复合材料中tac纤维间距和凝固速率的函数关系为，横向面积与凝固速率的函数关系为s = - 0 . 6597r 5 . 14 ， tac纤维体积分数在一定范围内随凝固速率变化。 |
| 5. | It was found that the interface morphology of ni , cr , al - tac eutectic in - situ composite evolved from plan to cell and then to dendrite with the increase of solidification rate , if the gradient retained constant . in the same time , the eutectic microstructure also evolved from rod to cell and then to dendrite
本工作发现，在温度梯度基本保持不变的条件下，随着凝固速率的增大， ni ， cr ， al - tac共晶自生复合材料的凝固界面由平界面向胞状及枝状界面逐渐转化。 |
| 6. | 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。 |
| 7. | On condition of controlling solid - liquid interface preferably and keeping low directional solidification rate , there were particular phenomena in tasi2 fibre development process . generally , it can be divided into three typical steps . the first was star - up period , the second was competition period , the third was stabilization period
在较好控制固液界面和较低的生长速率定向生长条件下，纤维相tasi _ 2生长过程有其独特的规律性，通常可以将其生长过程分为启动、竞争、稳定三个典型阶段。 |
