I couldn't find any sample codes for calculating A1 and A3 temperatures. So I tried to write one on my own. I was able to obtain A3 with a few iterations using the lever rule. However, A1 was difficult to calculate due to the potential coexistence of two FCC phases (austenite and TiC). I tried to differentiate them using the C or Fe content in each FCC phase but was unable to do that correctly. Would someone help? Thank you in advance.
