1. The components of the refining- modificator in refining electric aluminum was introduced, and the formulation of the refining- modificator was optimized using the orthogonal design experiment.

2. This paper deals with the Influence of modificator Na and P on castability of ZL108 alloy.

3. A proposal on using RE as a modificator and the method of complex modification by use of RE associated with other elements fo...

4. The result showed that titanate modificator is better than siloxane and PVA ( polyvinyl alcohol ) .

5. The effects of RE compound modificator on the mechanical properties and microstructure of high carbon high speed steel used for roller ring were investigated by SEM, EDS and EPMA.

6. The effects of compound modificator on microstructure, mechanical properties, wearing properties and damping properties of ZA27 alloy have been studied.

7. The experiment results showed the structure was refined and the properties were enhanced after adding modificator, such as rare-earth ferrosilicon.

8. In the present paper, the first experiments that restrained segregation of the casting of high leaded bronze by means of modificator consisted of lithium chloride or strontium chloride is reported.

9. A new type of Y base heavy rare earth modificator was developed.
