  改性剂
     The reason of the third-phase elimination by the modifier TBP is that R3NH+(H2O)3·Cl- could be split by TBP and form a huge cation R3NH+(H2O)3·O=P(OC4H9)3 that could be dissolved in inert diluent, and simultaneously Cl- would be dispersed in diluent as an equilibrium ion.

A systematic study has been made of the modification of Al-Si alloys with eleven individual rare-earth elements (La, Ce, Pr, Nd, Sin, Eu, Gd, Tb, Ho, Er and Y) and also mischmetal at a cooling rate of 70—80℃/min. The modifier was added into the alloys by the methods of both reciprocal reaction and electrolysis of corresponding binary molten salts of rare-earth chloride and KCl. From the metallographic observation, it was shown that Eu possesses the greatest modification ability, and La the next, and both of them are permanent modifiers. The modification ability of Ce, Pr, Nd and mischmetal are even weaker than that of La. It was also found that modification ability of rare-earth elements decreases rapidly with the decreasing of their atomic radii. The greatest modification ability of Eu may be referred to the leap of its atomic radius. Owing to the similar reason, Yb (not investigated) would be expected to be the another element possessing strong modification ability in the lanthanide. In the consequence of lanthanide, from Sm to Ho the modification ability is negligible. Finally, under the conditions mentioned above, Er and Y did not show any modification effect on Al-Si eutectic alloy at all. According to the information that the atomic radius of Ac (2.03(?)) is somewhat greater than that of La (2.02A) and the modification ability may become greater in the order Y-La-Ac of the periodic table, it is deduced that the radioactive element Ac may have even greater modification ability than that of Eu. Thus the strongest modifiers would be elements La, Sr and Ac set on an oblique straight line in the periodic table. Therefore, it is assumed that the modification ability of a modifier may be the result of a certain combination of the valence electron charge number, the atomic number and the atomic radius of the modifier.

用稀士熔盐电解法及熔盐直接反应法对Al-Si液态共晶合金分别定量添加了La,Ce,Pr,Nd,Sm,Eu,Gd,Tb,Ho,Er和Y共十一个单一稀土以及一个混合稀土的变质剂。通过显微结构分析系统地研究了在70—80℃/min冷却速度下合金的变质效果。发现Eu,(Yb)具有最强的变质能力,La次之,并发现其均为“长效”变质剂.Ce,Pr,Nb及混合稀土的变质能力稍低于La。稀土元素的变质能力随原子半径的减小而迅速降低.Sm以下已减弱至微不足道的程度。Eu和(Yb)的变质能力主要是与其原子半径的突跃增大有关。Er,Y不具变质能力。根据Eu和Ac原子半径的接近以及Y-La-Ac的同族规律,推测Ac将具有还要大的变质效果。据此总结了强变质剂Na,Sr,Ac在元素周期表中的斜线位置,认为变质剂元素的变质能力主要取决于其价电荷数,原子半径和原子序数的一定组合。

The effect of micro-amount element additions on the microstructures of Al-Ge and Al-Si-Ge eutectic alloys has been studied by means of metallographic method. For Al-Ge eutectics, no evidence was found of occurring any modification something like that exists in the Al-Si system. Some elements which belong to the ⅣB, ⅤB and ⅥB groups in the periodic table of elements seriously influence their microstructures and change the feather-like Al-Ge euteetic into block Ge crystals. In the other case, it appears to move...

The effect of micro-amount element additions on the microstructures of Al-Ge and Al-Si-Ge eutectic alloys has been studied by means of metallographic method. For Al-Ge eutectics, no evidence was found of occurring any modification something like that exists in the Al-Si system. Some elements which belong to the ⅣB, ⅤB and ⅥB groups in the periodic table of elements seriously influence their microstructures and change the feather-like Al-Ge euteetic into block Ge crystals. In the other case, it appears to move the eutectic point to the Al-rich side when some alkaline, alkaline earth and rare earth elements were added in this eutectic. The modifiers Na, Sr, La effective in the Al-Si system were scanned about their effects on the Al-Si-Ge system. In this ease, eutectic Si exists in modified clusters form and gradually dwindle their size with increasing the Ge content, finally they disappeared at the Al-Ge side. According to comparison of the modification between the Al-Ge and Al-Si systems, it was considered that the modification of Al-Si eutectic was mainly decided by the effects of modifier atoms on the epitaxial orientation relationship or decreasing the disregistry between {110}_(Si) and {100}_(Al).

用金相方法考察了微量添加元素对Al-Ge和Al-Si-Ge共晶合金显微结构的影响。ⅡB,ⅢA,ⅣA和ⅤA族元素对Al-Ge共晶结构并无影响;ⅣB,ⅤB和ⅥB族难熔金属影响较大,共晶Ge聚集为大块的结晶;碱金属,碱土金属和一些VⅢ族金属的加入,使Al-Ge共晶点向富Al方向移动。Al-Ge共晶不出现类似Al-Si共晶的那种变质现象.Al-Si-Ge系变质时,Si以变质的共晶团存在。根据Al-Ge和Al-Si结晶过程的对比,认为Al-Si共晶的变质,主要取决于变质剂原子对(100)_(Al)∥(110)_(Si)外延关系的影响。

The effect of 12 elements such as Li, Na, K, Mg, Ca, Sr, Ba, La, Sm, Y, Sb and Bi on the modification of the Al-Si eutectic alloys was systematically investigated by means of their microstructure observations. The range of modifying concentration for each modifier under various cooling rates was detected and their effects on microstructures of Al-Si eutectic alloys with same modifier concentration but varied cooling rates were also studied. A critical cooling rate, v_c, of modification is always presented for...

The effect of 12 elements such as Li, Na, K, Mg, Ca, Sr, Ba, La, Sm, Y, Sb and Bi on the modification of the Al-Si eutectic alloys was systematically investigated by means of their microstructure observations. The range of modifying concentration for each modifier under various cooling rates was detected and their effects on microstructures of Al-Si eutectic alloys with same modifier concentration but varied cooling rates were also studied. A critical cooling rate, v_c, of modification is always presented for each own modifier. The modification does not occur at a lower cooling rate than v_c with whatever the concentration of the modifier. The lower the v_c of a modifier, the stronger will be its modifying ability. Among these modifiers studied, the modifying abilities of Na, K, Sr and La with their v_c values lower than 40℃/min are the strongest. It seems to be suggested that v_c is available for a quantitative scale of the modifying ability assessment of a modifier.

借助显微结构法系统地研究了Li,Na,K,Mg,Ca,Sr,Ba,La,Sm,Y,Sb和Bi等12个微量元素对Al-Si共晶合金的变质作用。考祭了各变质剂在不同冷却速度下的变质浓度范围以及在添加变质剂浓度相同时,不同冷却速度对Al-Si共晶合金显微结构的影响,发现各种变质元素对Al-Si合金变质时均具有一变质临界冷却速度v_c。冷却速度低于此值时,任何浓度的变质剂均不能引起合金的变质。变质剂的v_c值愈低,变质能力愈强。其中以Na、K、Sr和La变质能力最强,其v_c值均低于40℃/min。据此认为v_c可作为评价变质剂变质能力的定量标准。
