INFLUENCE OF ALLOYING ELEMENT TITANIUM ON FORMATION OF D-TYPE GRAPHITE
-
摘要: 从两个方面分析了合金元素Ti对D型石墨形成条件的影响。Ti促进了初生奥氏体枝晶的析出,影响了奥氏体枝晶的形态,为D型石墨的形核和生长创造了有利的条件;Ti对石墨形核和长大的影响与其含量有关,当Ti含量>0.1%时,它阻碍石墨化的作用占主导,有助于形成D型石墨。Abstract: The influence of alloying element Ti on the formation of D-type graphite was analyzed from two aspects. Ti promotes the precipitation of primary austenitic dendrite, affects the morphology of the austenitic dendrite, and creates the avail condition for nucleation and growth of D-type graphite. The influence of titanium on nucleation and growth of graphite is connected to its content. When the content of Ti > 0.1%, it will primarily holdback graphitizing, and is helpful to the formation of D-type graphite.
