“铁碳相图”与“固态相变”

“Iron-Carbon Phase Diagram” and “Solid-State Phase Transformation”

摘要: 本文从固态相变的角度，系统地分析铁碳相图中固相线以下的相变，进而加深对相变线(相区的分界线)的认识，来理解其多重含义。另一方面，从固态相变的角度理解铁碳合金的多种状态，为建立材料微观组织结构与宏观性能之间的内在联系提供一种思路，为“铁碳相图”与“固态相变”的教学过程提供一定的借鉴与参考。

Abstract: In this paper, from the perspective of solid-state phase transformation, a systematic analysis of the phase transformation under the solid line during iron carbon phase diagram was studied, and then deepens the cognition of phase transformation line (phase boundary), further to understand their multiple meanings. On the other hand, a variety of states of the iron carbon alloy were understood by the perspective of solid-state phase transformation, and it can provide a train of thought for establishing inner relation between material microstructure and macro properties, also provide a certain reference to the teaching processes of iron carbon phase diagram and solid-state phase transformation.
