| Abstract | ||
| An automotive brake rotor material has noticeable properties where, the gray cast iron is superior for that application. In this work, a detailed description of the process of improving mechanical properties and thermal conductivity for the brake rotor material that made from a gray cast iron type (A according to ASTM A247). The study accompanied with a full description of the microstructure evolution in each step of heat treatments that followed. It is found that, the quenching followed by a tempering process at 500°C can give a better UTS, and elongation at the same numbers of hardness. Thermal conductivity which is the prime requirements in brake rotor applications also improved according to the microstructure evolution. | ||
