灰铸铁的孕育和合金化是提高其力学性能和使用性能的重要途径，其中铬是最常用合金元素之一。铬是强烈稳定珠光体的元素，能显著提高灰铸铁的强度。但铬强烈增加铁水白口倾向并具有较高熔点，阻碍了其在灰铸铁中的广泛应用。利用铬提高强度的有利一面，抑制其白口倾向并降低其?
Inoculation and alloying of gray cast iron is an important way to improve its mechanical properties and service properties, of which chromium is one of the most commonly used alloying elements. Chromium is a strongly stabilized pearlitic element that can significantly increase the strength of gray cast iron. However, chromium strongly increases the whiteness of molten iron and has a higher melting point, which hinders its widespread application in gray cast iron. Use of chromium to enhance the strength of the beneficial side, inhibit its white tendency and reduce it?
