摘要
针对液态成型原理实验课程中铸件产生的缺陷,在大学生创新基金项目中建立了凝固过程瞬态温度场的数学模型以及硬度随熔炼次数变化的函数关系,结果表明随着熔炼次数的增加ZL104返回料硬度降低,成分偏析加剧。通过实验教学与创新基金项目的有效结合,对实验教学方法进行了新的思考和探索,提出以项促学和精英模式的人才培养方案,不仅增强了学生的创新意识和实践能力,而且提高了实验教学质量。
According to the fault of casting formation during the ＂liquid forming principle＂ experimental courses,the mathematical model of transient temperature field on the solidification process and function relation between hardness and melting times have been established in the college innovation fund projects.Results show that hardness of ZL104 return material is reduced and composition segregation intensified with melting times increased.Through the effective combination of experimental teaching and innovation fund project,the experimental teaching methods have been thought and explored,to promote learning and elite mode of the talent training scheme,which can not only enhance the students＇ innovation consciousness and practical ability,but also improve the quality of experimental teaching.
