| Abstract: | GCr15 steel with upper hainite was sub-critically annealed. The annealed structure was carefully ohserved. The special quenching and aging processes and their operating for GCr15 steel were introduced. The modified austenite （A2） and its transformation to upper bainite as well as the upper bainitic structure in the GCr15 steel were discussed according to heat treatment principle and Mullin, SeKerKa boundary destruction. |

| Keywords: | GCr15 steel annealed structure secondary recrystallization flow stress boundary destruction |
