Page TTT diagrams for eutectoid and steel alloys. Author: mveiseh Created Date: 9/26/ AM. Mar 03, · Hi, I’m doing heat treatments on a steel which is a nickel-chromium-molybdenum steel containing also manganese and carbon.
Anyone knows which and how I can find the appropriate phase diagram for this low-alloy steel? an AISI steel.
The calculated response was subsequently tested using the experimentally measured CCT data for a different AISI steel. As the characterization of continuous cooling kinetics requires knowledge of the phase diagram, a mathematical model based on thermodynamic equations is used to derive the phase diagram for this steel.

In other words, for a given alloy, the phase diagram can show the phases and percentage of each phase present at a specific temperature and alloy composition.
It can also show how the phases are affected by changes in the alloy composition, temperature, or both.Martensite | RevolvyCarbon Steels And The Iron Phase Diagram – Best Diagram For Cars
