加锑(Sb)获得珠光体D型石墨 (D—Gr)铸铁的研究

STUDIES ON MAKING D-TYPE GRAPHITE (D-Gr) CAST IRON OF PEARTITIC THROUGH ADDING STIBIUM

本文研究了加入锑对珠光体“Ｄ—Ｇｒ”铸铁强度的影响，结果表明：通过加入锑得到９５％的珠光体基体的“Ｄ—Ｇｒ”来获得高强度、高硬度的铸铁是切实可行的。

This paper disscusses the effects of the strength with the pearlite 'D Gr'Cast iron by adding stibium,The result shows that it is practical to get high strength and hardness of D - type graphite cast by the way of getting 95% pearlitic- based D - type graphite with adding stibium
