I am trying to answer a question using the TTT diagram of steel that is given to me in my text. I know how to use the diagram, but the book assumes some prior technical knowledge of steel. It gives the information that the steel samples are 0.3 mm thick hot-rolled strips of 1080 steel, and then it gives me a heat-treating schedule and asks me to determine the final microstructure. I know that 1080 means 0.8% C, but I do not know if the thickness or hot-rolling affect the resulting microstructure. Initially, the sample is held at 860 C for an hour.
Any help would be appreciated. I am not looking for an answer or tutorial on the TTT, but if someone can explain to me if and how hot-rolling and thickness affect microstructure.
Thanks!
