The paper presents a study on the grain size and tensile strength of annealed ultra-low carbon (ULC) steel containing wt.% carbon (C) and various contents of copper (Cu). The annealing temperature was predetermined at 700, 800, and 900 °C with the same holding time of 15 minutes and a slow cooling rate. |
