铁碳合金相图是人类经过长期实践并进行大量科学实验总结出来的。它主要研究铁碳合金的成分、温度和组织结构之间关系的图形。这张相图的字母、数字、点、线条较多,中职学生在学习过程中较困难,教师可通过不同的教学方法使学生初步地了解、深入地理解并掌握铁碳合金相图。 Iron-carbon alloy phase diagram is the human after a long period of practice and a large number of scientific experiments summed up. It mainly studies the composition of iron-carbon alloy, temperature and the relationship between the structure of the graph. This phase diagram of the letters, numbers, points, lines more secondary vocational students in the learning process more difficult, teachers through different teaching methods to enable students to understand the initial understanding of and master the iron carbon alloy phase diagram.
