After adopting spinning nuzzle method , a lot of tic particles were got even at 720 , and alti10 master alloy will be dissolved more easily 在改用旋转喷头加入c后，即使在720 ，也可以获得较多的tic ，并且alti10中间合金也更容易溶解于al - si合金中。
And yet different size and morphology of tial and tib2 can result in the remarkable differences of refining effect when we refine al and al alloys by the master alloy 而且在用这些中间合金细化铝及其铝合金时，我们发现含有不同尺寸形态tial _ 3晶体和tib _ 2化合物的中间合金对铝及其铝合金的细化效果具有明显差异。
As being applied to production can save raw material and reduce cost . the experiment prosposes al - ti - b - re master alloy and theoretical analyses know that it can overcome some weakness of al - ti - b master alloy and belongs to ^ a grain refiner needing studied further 试验还提出了aitibre中间合金，理论分析表明，它能够克服aitib中间合金的一些缺陷，是一种有一待于我们进一步深入研究的细化剂。
Moreover , the heredity of al and al alloys own structure morphologies has been discussed . block or flack - like tial and bar - like or particles tib2 can be obtained by means of fluoride salt method melting at 800 c ~ 1100c under the other same condition 用氟盐法制备中间合金时，在其它条件相同的情况下，改变熔炼温度( 800 1100 )可以得到含有块状和针片状形态的tial _ 3晶体和条状与颗粒状tib _ 2化合物的中间合金。
Experimental results show that the order of fluoride salt being put in and flux type also influences the phases constitution , morphology , distribution and absorbent rate of ti and b . the experiments on remelting master alloys and al or al alloys at a certain temperature range show that the phases constitution and size have a remarkable heredity 试验结果表明，不同的氟盐加入顺序和熔剂种类的不同也直接影响着中间合金中化合物的相组成、形态、分布以及中间合金中ti 、 b的实收率等。在用纯钛颗粒法制备中间合金时，熔炼温度的改变只能影响tial _ 3晶体的尺寸大小，而无法改变其形态。
Melting temperature , putting in sequenceiof raw material , chemical composition and flux type affecting structure morphologies of altib master alloys in producing process of master alloys has been systematically investigated from the view of al - ti - b master alloys heredity . and we study the effect that different master alloys refine commercial al and al alloys 本论文主要从altib中间合金遗传性的角度出发，系统地研究了在制备中间合金的过程中，熔炼温度、原料加入顺序、 ti含量、凝固速度、原料的化学成分和熔剂种类等对中间合金组织形态遗传性的影响。
