例句與用法

  1. The amount of nb3si / nb5si3 increases , their morphology tends to be more regular , their distribution becomes more homogeneously with the increasing of withdrawing rate . the microstructure is better oriented along the longitudinal axis of the samples when the withdrawing rate is between 0 . 6 and 6 . 0mm / min . at the same withdrawing rate , the microstructure changes from the beginning part to the ending part of the samples
    鈮?硅基rmics材料原始鑄態組織由初生nb基固溶體和在其間分布的nb基固溶體+硅化鈮共晶團組成;隨著抽拉速率的增大,定向凝固共晶組織中硅化鈮強化相細化、數量增多、分布趨于規則和均勻,定向效果顯著;在相同抽拉速率條件下,區熔試樣的組織從起始段到終止段發生了改變。
  2. The cracks extend along the matrix / strengthening - phases interfaces and form the cleavage steps and tear ridges . there appear some very small dimples on the fracture surfaces of the directionally solidified samples , which come from the nb - based solid solution particles in the big plates of the strengthening phases , but no dimples on the fracture surfaces of the as - cast sample . it can be concluded from above results that niobium - niobium silicide based in - situ composites ( rmics ) with a uniformly orientated microstructure can be produced by the ebfzm with high temperature gradient , and their mechanical properties can be increased
    隨著抽拉速率的提高和硅化鈮強化相間距與尺度的減小,材料的室溫拉伸強度和斷裂韌性均有提高, _ b最高可達778 . 4mpa , k _ ( ic )達到了46 . 3mpa ? m ~ ( 1 / 2 ) ;試樣的拉伸斷口基本表現為脆性解理斷裂的花樣,裂紋沿基體強化相界面繞過強化相進行擴展,在裂紋擴展方向存在解理臺階,并形成撕裂棱。
