铁碳合金平衡组织观察实验的教学探讨

The teaching discussion of the observation experiment of iron-carbon alloy balance organization

根据Fe—Fe3C相图分析铁碳合金在平衡状态下的显微组织，从纯铁的同素异构体到铁碳合金的基本相，从认识Fe—Fe3C相图到分析铁FeFe3C相图，让学生在理解的基础上掌握铁碳合金基本组织及形态。

According to Fe-Fe3C phase diagram analysis, the iron carbon alloy microstructure under state of balance, from ferrite allotrope to the iron carbon alloy basic phase, from the understanding Fe-Fe3C phase diagram to the analysis Fe-Fe3 C phase diagram, enables the student to master the iron-carbon alloy basic organization and shape in the understanding foundation.
