例句与用法
- The result of experiment showed that the reaction between ti and c is a thermodynamic course , when 2 wt % mg is added to melt , it can restrain the formation of fragility phase al3ti , and gained al matrix composite which contained tic reinforced particles only . because mg reacts with the forms a micro - high temperature field around the oxide around the graphite particles and the oxygen gas which is brought by the immersion bell , and the reaction gives out a lot of heat energy , thus forms many high micro - fields in melt , which prompt the reaction between the al and ti
加入适量的mg ( 2wt )可以抑制tic al复合材料中的脆性相al _ 3ti的产生，生成仅含tic的铝基复合材料；由于活化剂镁在体系中与石墨颗粒周围的氧化物、以及外来的氧反应放热，在熔体中形成微高温区，促进al - ti反应，同时， al - ti反应也是放热反应，因此体系中的内能急剧增大，促使al _ 3ti分解以及ti朝c颗粒扩散，缩短反应的孕育时间。 - Al these can increase the nucleation rate , so the tic particles become smaller and disperse more homogeneous , and the volume fraction of tic is increased . when 0 . 5wt % rare earth ceo2 is added to melt , the surface tension of melt is decreased and fluidity is enhanced , accordingly it enhances the diffusion rate of ti to c particles during the course of reaction and prompts the formation of tic
加入0 . 5wt的稀土ceo _ 2增大了熔体的表面张力及流动性，从而在反应阶段增大ti原子朝c颗粒的扩散速率，促使tic颗粒生成，以及在反应完成后增大tic颗粒朝熔体中扩散的速率，促使tic颗粒的形核。 - The forming - nucleus drive power could form numerous little crystal nucleus under natural melting temperature . the formation of tic particles in the melt could be divided into two phases which was forming - nucleus and growth . the forming mechanism of tic was : melting ti first surrounded c , then ti melting in the alloy and c formed a complicated reaction mesosphere on the carbon surface
根据热力学及动力学分析，认为在碳颗粒界面处tic的形核率很高，形核驱动力足以在正常的熔炼温度下形成众多的小晶核；熔体中tic颗粒的合成可分为形核与长大两个阶段，其形核机制为：首先活性ti原子包围c ，溶入合金中的ti与c在碳表面形成一复杂反应中间层，随着反应进行， ti和c颗粒不断减少，生成的tic不断弥散分布于熔体中；其长大过程伴随着tic颗粒的相互堆砌、聚集和形态规则化。
