本文通过综合分析和回归分析,考察在少加废钢、高碳当量、低合金化条件下,若干组织因素与灰铸铁强度之间的关系。结果表明,奥氏体枝晶数量、石墨数量、石墨尺寸和基体显微硬度,是影响高碳当量灰铸铁强度的几个重要组织因素。 Through comprehensive analysis and regression analysis, this paper examines the relationship between the strength of gray cast iron and the number of organizational factors under less-added scrap, high-carbon equivalent and low-alloyed conditions. The results show that the number of austenite dendrites, the amount of graphite, the size of graphite and the matrix microhardness are several important factors affecting the strength of high carbon equivalent gray cast iron.
