• Above this point the hardness can be increased only slightly, because steels above the eutectoid point are made up entirely of pearlite and cementite in the annealed state.

    高于由于超过共析完全由珠光体退火状态碳体组成,硬度增加并不多。

  • It was found by experiments thatboron increased the growth rate of pearlite, both in hypoeutectoid and eutectoid steels.

    硼有加速珠光体成长作用,无论共析共析中皆有同样的现象产生。

  • The resulting structure is a mixture of primary or pro-eutectoid ferrite (ferrite that formed above the eutectoid reaction) and regions of pearlite.

    作为结果的组织结构初步共析素体(在共析反应前的铁素体)部分珠光体混合物
