| 1. | In instable region the precipitation mechanism of " phase is congruent ordering followed by spinodal decomposition , and ordering occurs prior to clustering
失稳区合金相的早期沉淀机制为：等成分有序化+失稳分解，有序化先于原子簇聚发生。 |

本文以al - li合金为对象，通过计算机模拟研究了外势场对单原子能量的影响和原子间相互作用势对( al _ 3li )相沉淀机制的影响。 |
| 4. | 6 . through analysis and discuss of the precipitation mechanism of cr phase , it can be deduced that primary ( cr ) phase exhibits petal shape or triangular due to solute and heat flow in local fluid
6通过对初生相( cr )相析出机制的初步分析和探讨，认为由于熔体局部的溶质和热流波动，初生相的生长形态有花瓣状或三棱形。 |
| 5. | It is firstly found that for alloys in transitional region , with enhancement of atomic interaction energy , pregnant period of " phase is shortened dramatically , and process of clustering accelerated remarkably , stages of growth and coarsening of " phase brought forward , i . e . precipitation mechanism of alloy in transitional region incline to that of alloy in instable region
首次发现，随着原子间相互作用势的增加，过渡区合金中有序相的孕育期明显缩短，原子簇聚过程明显提前，相的长大和粗化阶段也有所提前，即促使过渡区合金的沉淀机制偏向失稳区合金。 |
| 6. | The sequence is : non - classical ng supersaturated solid solution spinodal decomposition the variation in precipitation mechanism of 8 " phase in intermediate region is systematically investigated firstly , and it is found that with the increase of composition the precipitation characteristic transforms from that of metastable to instable region gradually
首次发现l12有序畴之间首先形成较宽的重合位置点阵，随时间延续，重合位置点阵逐渐向ll :结构转变，在两有序畴之间形成反相畴界，随后，由于合金发生分解，反相畴界被有序一无序界面替代。 |
| 7. | No incontinuous transition has been found at mean - field spinodal lines and the transition of precipitation mechanism transform gradually across the mean - field spinodal lines . precipitation mechanism at disordering instability line is non - classical nucleation and growth , similar to those in metastable region , and precipitation mechanism at ordering instability line is non - classical nucleation and growth , followed by spinodal decomposition , similar to those in instable region
在不同的区域，粗化有不同的表现形式:在亚稳区，与(形核)长大交叠;在失稳区，与失稳分解交叠;在过渡区，与长大和失稳分解混合机制交叠。 |
