作者用99.96％的多晶掺碳镍从390—450℃作滞弹性蠕变及应力驰豫试验,所测得蠕变量比纯镍低得多。用侣单晶从360—440℃作滞弹性蠕变及应力驰豫试验,所测得蠕变激活能为(267520±8360)J/mol,比纯侣体积自扩散激活能大得多。因此,结合文[1],可以认为多晶在较高温度(中沮)下的滞弹性蠕变机制与晶粒间界自扩散机制相似。
Using 99.96% polycrystalline carbon-doped nickel from 390-450 ℃ for the anelastic creep and stress relaxation tests, the measured creep is much lower than pure nickel. Coupling single crystal from 360-440 ℃ for the anelastic creep and stress relaxation test, the measured activation energy of creep (267520 ± 8360) J / mol, than pure volume of self-diffusion activation energy is much larger. Therefore, in conjunction with [1], it is believed that the mechanism of the anelastic creep of polycrystalline at higher temperatures (moderately depressed) resembles the self-diffusion mechanism of grain boundaries.
