because the austenite to ferrite is already destined to be an incomplete reaction. Notice how the A to F doesnt end in the green portion, meaning there were some austenite available to change to pearlite. For the M + F + P + B, the line crosses the ferrite region, then passes into the pearlite route. however, you can see that it crosses the black line instead of the green line, meaning the transformation to pearlite is incomplete. then it passes through bainite, which also didnt have a green line that indicate full transformation. Lastly, the remaining enters the martensite region.
this guy fosho going to heaven
Thank you for a very clear and concise explanation; much appreciated!
you are the best! Thank you
Well done
Thank you sir.
Thank You!!
Why it become M+F+P+B instead of F 100% cuz the line pass through A to F (complete) 🥺🙏🏼 pls help💖
