WebMar 6, 2016 · Low carbon steels – Hypo-eutectoid steels. The Fe-C phase diagram provides temperature-composition map of where the two phases (austenite and ferrite) occur. It also indicates where mixtures of these two phases can be expected. The Fe- C phase diagram is shown in Fig 2. In pure iron, austenite transforms to ferrite on cooling …

Carbon Steels and the Iron-Carbon Phase Diagram – IspatGuru

WebFe–C phase diagram The vast majority of steels are in the austenitic condition at tempera-tures in excess of 900 C. Austenite has a cubic–close packed crystal structure and tends to decompose into ferrite (body–centered cubic) and cementite (Fe 3 C). Steels with a carbon concentration less than about 0.8 wt% are hypoeu- WebMay 15, 2024 · Recent work [215] on the Fe-S-C ternary phase diagrams has allowed a more accurate determination of the phase boundaries from 1600 to 1200 • C as shown in Figure 9 (a).
