 等轴组织 [děng zhóu zǔ zhī添加此单词到默认生词本
equiaxed structure

  1. 焊道显微组织为均匀且细小的等轴晶粒,而5083中粗大的晶出物亦细化且圆钝化。
    Uniform and refined equaxial grains could be observed in welding zone, and the coarsening intermetallic compounds of 5083 are refined and spheroidized after welding.
  2. 文摘:对球铁金属型静凝固与振动凝固的结晶组织对比表明:后者柱状晶方向性生长较弱,等轴晶出现较早,且两者的晶粒均较细,全断面硬度较高且分布均匀;前者枝晶奥氏体内溶质偏析大,有畸变夹杂团块。
    Abstract: The crystal structures obtained by static solidification and vibration solidification were compared.It was showed that,in the case of vibration solidification,the orientation growth of the columnar crystal was not obvious,the equiaxial crystal appeared more early.The grains of both types of crystals were quite fine,hardness in the full section was relatively high,and the hardness distribution was uniform.In the former case,the solute segregation in dendritical austenite more severe,and there were lumps of distortion inclusion.
  3. 摘要为了验证复式结晶器在提高铸坯等轴晶率方面的作用,分析比较了复式结晶器和传统结晶器的传热特征,并检测了两种结晶器所浇注铸坯的宏观组织
    The effect that combined mold can increase the proportion of equiaxial crystal of billet was confirmed by comparing its heat transfer character with that of traditional mold and measuring the macrostructure of the billets produced by these two molds.
