细化变质对亚共晶Al-Si合金熔体结构的影响
This paper sums up the research methods of melting structure and the process of research on melt structure of aluminum and aluminum alloys, and especially gives a detailed introduction to Al-TM-X和 Al-Si-X system alloys.
综述了最近几十年来液态结构研究方法、铝及铝合金熔体结构研究的进展,特别是对Al-TM(过渡族元素)-X和Al-Si-X合金系做了详细介绍,希望为研究更高质量的铝合金熔体,精确控制铝及铝合金中的相组成提供理论指导。
The results show that, the melt-superheating treatment between 1 600 ℃ and 1 650 ℃ can cause a slight decrease in nitrogen content of the alloy owing to the refinement; but the melt-superheating treatment above 1 700 ℃ begins to increase the nitrogen content of the alloy because it changes the melt structure; and when the melt-superheating temperature.
结果表明 :在 16 0 0～ 16 5 0℃进行熔体过热处理 ,合金中的氮含量因精炼作用而略有降低 ;但当过热温度达到 170 0℃时 ,由于熔体结构的变化而使合金开始吸氮 ;当过热温度达到 185 0℃时 ,合金中的氮含量由原来的 0 。
The results indicated that EPM process makes the liquid structure of the alloy change: The activity of Pb i.
分析认为,由于电脉冲处理作用,合金熔体结构发生了改变,使熔体中Pb的活度提高, 进而引起溶质平衡分配系数的变化,导致凝固前沿的溶质富集减轻,溶质分布情况发生改变, 促使树枝晶向球状组织转化,并且使凝固组织发生细化。
And the conventional view of liquids is that the liquid structures and properties change gradually with temperature from T_L to the critical point.
关于液体结构和性质对温度的关系,传统理论一直认为从TL到液-气临界点为连续渐变;然而,近年来的研究却观察到了不同于上述传统理论的新的物理图像;一些合金熔体在高于TL数百度的温度范围,可发生温度诱导液-液转变(TI-LLST),即熔体结构及诸方面性质随温度发生非连续的变化。
