In the experience Salt、Sb and thulium can change primary Si and eutectic Si through changing the morphology, but the effect of modification is very defferent.
其中钠盐的变质效果强,锑次之,稀土变质效果最差;变质剂对Si相的变质主要是通过孪晶凹角沟槽机制进行的。
-
Salt is the best. Sb is better than thulium. The modification of modifying elements addition on Si takes effects through TPRE mechanics.
变质通过"毒化"孪晶凹角而抑制Si相在择优方向上的各向异性生长,迫使Si相产生多重孪晶并沿其它方向进行各向同性生长,长成等轴状。

The results show that the undissolved silicon particles in the melt become the cores of primary silicon precipitated in solidification and there is a close relationship between the shape of primary silicon and undissolved silicon particles. The growth of silicon follows not only the twin plane re-entrant edge mechanism, but also layer mechanism as well. Meanwhile, the shape of primary silicon also relies on kinetic surroundings, such as the transmitting of solute. At higher overheating temperature, the shape of primary silicon becomes the star-shape and tree-shape.
结果表明:重熔过程中熔体中未溶解的硅相粒子,在凝固过程中可成为初生硅生长核心,并且未熔颗粒与初生硅形状之间存在明显对应关系;初生硅的生长机制不是惟一的,既可以以孪晶凹角机制生长,还可以以层状机制生长,初生硅最终形状还要取决于溶质传输等动力学环境;随着熔体过热温度的升高,凝固组织中初生硅形状由多边形向星形及树枝状转变。

Beginning with these angles of the niche, the wall extended along the Rue Polonceau as far as a house which bore the number 49, and along the Rue Droit-Mur, where the fragment was much shorter, as far as the gloomy building which we have mentioned and whose gable it intersected, thus forming another retreating angle in the street.
和这斜壁两角相连的墙,在波隆梭街方面,一直延伸到第四十九号房屋,而在直壁街一面??这面短多了??直抵先头提到过的那所黑暗楼房的山尖,并和山尖构成一个新凹角。
