摘要
“材料科学基础”是材料加工工程专业学生必须掌握的专业基础课程,其相关工艺实验是培养学生工程实践能力和科技创新能力的有效途径。其中,加工硬化实验环节多、周期长、大型仪器数量有限,不适合开展大规模教学,随着学生培养规模的上升,实现多人的标准化实训和考核已成为材料加工工程专业本科实验教学的瓶颈之一。本文通过对加工硬化工艺及其微观机制进行虚拟仿真,使无法在传统课堂上完成的实验教学能够完成,弥补了实体教学的不足,加强了学生对基本概念的理解和掌握,达到了培养学生工程实践和科技创新能力的目的。
“Fundamentals of materials science”is a professional basic course for the undergraduates who study on materials processing engineering.Its related process experiments are an effective way to cultivate the students’engineering-practical and technological-innovative abilities.Among these experiments,too many steps the long periods of time,and the limited instruments have restricted the large-scale teaching and learning for work-hardening experiment.It is difficult to achieve standard training and assessment for many students.With the rising of the number of the students,it has become one of the bottlenecks of undergraduate experimental teaching in material processing engineering.By means of the virtual simulation of the work-hardening process and its microscopic mechanism,the experimental teaching that could not be completed in the traditional classroom can be achieved,which compensates the deficiency of the physical teaching,strengthens the students'understanding and mastery on the basic concepts,and achieves the purpose of cultivating the students'engineering-practical and technological-innovative abilities.
