置换固溶体

结果发现，Cu固溶在W中，并形成了置换固溶体。

The results show that Cu solubilizes in W and the substitutional solid solution formed .

置换固溶体可增加断裂激活能，并随着合金元素含量的增加而增大；间隙固溶体断裂激活能略有减少。

The substitutional solid solution would increase activation energy of fracture with the content of alloy element , and the interstital solid solution would decrease slightly the activation energy of fracture .

结果表明：影响铁素体球铁曲轴硬度的主要元素是硅，硅溶于铁素体（-αFe）形成置换固溶体，造成晶格畸变，引起硬度提高。

Silicon was the main element which dissolved into ferrite to form substitutional solid solution , and caused lattice distortion and increased hardness .

由X衍射实验判定，Ni-W合金镀层足以Ni为溶剂、W为济质的置换型固溶体，呈面心立方结构。

A displacement solid solution made up of solvent Ni and solute W was determined by X - ray diffraction experiment .

亦考量结构特徵如：晶粒、有格隙型固溶体和置换型固溶体、析出物、第二相颗粒和共晶。

Also considers structural features : grain size , interstitial and substitutional solutes , precipitates , second-phase particles , and eutectoids .
