【摘要】 从球化率、球形度、分散度三个方面着手,首次利用模糊数学建立了球墨铸铁球化等级的评价模型,借助于“球铁金相图片分析系统”应用软件对GB9441—1988球墨铸铁金相检验标准的球化分级图进行了处理和分析,对模型进行了修正,得出了一个较为科学的、全面的球铁球化等级的模糊评价体系。该方法可扩展应用于材料的组织评定,对推动定量材料学具有积极作用。更多还原

【Abstract】 Analyzing nodularity,sphericity and dispersivity,afuzzy evaluation model for the nodulizing grade of nodular castiron is firstly set up by means of fuzzy mathematics. In order tomodify and verify the model, many microstructure of all kindnodulizing grade of China state standard(GB9441—1988) areanalyzed and summarized by the system of image analysis ofthe microstructure of nodular cast iron. Finally, a scientific andoverall fuzzy evaluation model for the nodulizing grade ofnodular cast iron is acquired.The method can be used to evalu-ate microstructure of other materials, and the result showed thatthe system has an important effect for pushing on quantitativemetallography.更多还原
