本科生毕业论文设计 题目 304不锈钢变形与磁性 作者姓名 指导教师 所在学院 专业（系） 班级（届） 完成日期 年 月 日摘 要 本课题为304不锈钢的变形与磁性，主要研究304不锈钢在变形后是否会产生磁性，变形的大小对磁性的利弊影响。如果产生磁性就会产生有利有弊的两面。针对这一现象，分析其在工业生产中会带来什么影响，会产生什么作用。对于有利的一面要在今后的生产中要加以利用，对于不利的一面要在加工过程中要避免其产生磁性，防止产生不利的影响。扬长避短从而发挥好设备或零件本身的作用，避免零件或设备失去本身的功能。 本文第一章分三小节概述了此次课题研究304不锈钢的变形与磁性的背景、意义和现状。第二章讲解304不锈钢的性能，其中包括304不锈钢的选材，物理性能以及化学性能，本章的研究分析为第三章实验的开展做了铺垫。第三章主要通过实验来探究304不锈钢变形产生磁性的原因，通过实验数据对其原因进行了有力的证实，为本课题研究的重点。第四章针对这次课题实验产生的数据及结果进行分析，对304不锈钢变形与磁性的利弊及发展前景做出了概述。第五章综合以上几章的分析与研究，对这一课题进行了总结。 关键词：304不锈钢 变形 磁性 Abstract The topic of this thesis is the deformation and magnetism of the 304 stainless steel. It mainly does research on whether deformation can make magnetism. It also studies the advantage and disadvantage bringing by deformation. If the deformation of 304 can produce magnetism, it has two aspects of advantage and disadvantage. According to this phenomenon, this thesis attends to analyze its impact on the industrial production and its function. As for the good aspect of it, people can make use of this in later production. As for the negative aspect of it, people can try to avoid the magnetism of deformation and its bad effect. Making use of the advantage and avoiding the disadvantage can play a good role of the equipment and its components. Doing this, it intends to avoid the loss of the function of the equipment and its components. The first chapter of this article has three sections to summarize the background, significance and current situation of the 304stainless steel’s deformation and magnetism. the second chapter explains the function of the 304 stainless steel. It includes the material of the 304 stainless steel, its physical properties and its chemical properties. The research and analysis of this chapter contribute a lot for the study of the next chapter. The third chapter in order to explore the reasons of the magnetism bringing by the deformation of the 304 s
