Step 1I'll solve this problem by explaining the scientific reasoning behind the iron-carbon phase diagram's carbon percentage limit.
Step 2: Understanding the Iron-Carbon System
The iron-carbon phase diagram is fundamental to understanding steel and cast iron metallurgy. The diagram is limited to 6.7% carbon because this represents the maximum carbon solubility in iron at the eutectic point.
Final Answer
The iron-carbon phase diagram is limited to 6.7% carbon because this represents the maximum carbon solubility in iron at the eutectic point, beyond which the material's fundamental metallurgical properties fundamentally change.
