Brief description of the role of silicon in cast iron (Qufu Longxiang Smelting Casting Accessories Co., LTD.)
(1) The carbon content at eutectic and eutectoid points decreases with the increase of silicon content;
(2) The addition of silicon results in a three-phase coexistence zone of eutectic and eutectoid transitions.
(3) The influence of silicon on the eutectic temperature of stable system and mesostable system is different because the temperature range of eutectic and eutectoid changes;
④ The increase of silicon also reduces the austenite region on the phase diagram.
