The grain size is an important factor that determines the mechanical properties of materials. Both the temperature and time of heat treatment, and the precipitation particles have significant influence on the grain size. An investigation is conducted on two alloys, with or without vanadium addition, under different heat treatment schedules. The grain size is observed and calculated by optical microscope and computer‐based image analyzer. The precipitation is analyzed using TEM. The influence of temperature and time is greater in alloy A than B, and precipitation is more effective for the grain refinement.
