surface area, and the distribution is more even than at the slab center. After 580 ℃/(4-12 h) treatment, the distribution is uneven with no precipitation at the grain boundary and inner, and the precipitation size is small and the density is high. With the increase of temperature, the precipitation distribution becomes more even with lower density and bigger size. The HV hardness is uneven......
