[问]在铸铁中加铝可细化石墨,加矽也可细化石墨,加镁可球化石墨。在元素周期表上看来,镁在铝的左边,这是否意味着靠近镁左边的元素如钠等,也可使石墨球化。而矽在铝的右边,这是否也意味着靠近铝右边的元素如磷等,也可以使石墨细化。 [Q] Aluminum can be refined in cast iron graphite, plus silicon can also be refined graphite, magnesium and nodular graphite. Appears on the periodic table of elements, magnesium is on the left of the aluminum, does this mean that elements such as sodium near the left side of magnesium can also make graphite nodular. And silicon on the right side of aluminum, does this also mean that the elements near the right side of aluminum, such as phosphorous, can also refine the graphite.
